Editor’s note: Today marks the 53rd anniversary of the Apollo 1 fire that killed three astronauts during a routine test on the launchpad. The test was a dress rehearsal for the Apollo 1 crew — Gus Grissom, Ed White and Roger Chaffee. The goal was to check out the command module, NASA’s first spacecraft that would take astronauts to the Moon.
Following is an excerpt about the fire from the book “Eight Years to the Moon: The History of the Apollo Missions” by Nancy Atkinson. The book tells the unique personal stories of over 60 engineers and scientists who worked behind the scenes to make the Apollo program possible, and is filled with stories of the dedication and perseverance it took to overcome the challenges, hurdles and conflicts of doing things that had never been done before. It provides a glimpse into the lives of some of the hundreds of thousands of people who made it possible to land humans on the Moon. While many of the stories in the book are fun and heart-warming, this excerpt shares the incredibly heart-breaking event that shocked the country and halted the Apollo program as NASA scrambled to figure out what went wrong.

KENNEDY SPACE CENTER VISITOR COMPLEX, FL – NASA unveiled a new tribute exhibit honoring three fallen astronaut heroes 50 years to the day of the Apollo 1 tragedy on January 27, 1967 when the three man crew perished in a flash fire on the launch pad during a capsule test that was not considered to be dangerous.
The Apollo 1 prime crew comprising NASA astronauts Gus Grissom, Ed White II and Roger Chaffee were killed during routine practice countdown testing when a fire suddenly erupted inside the cockpit as they were strapped to their seats in their Apollo command module capsule, on a Friday evening at 6:31 p.m. on January 27, 1967.
“It’s been 50 years since the crew of Apollo 1 perished in a fire at the launch pad, but the lives, accomplishments and heroism of the three astronauts are celebrated in a dynamic, new tribute that is part museum, part memorial and part family scrapbook,” says a NASA narrative that aptly describes the exhibit and the memorial ceremony I attended at the Apollo/Saturn V Center at NASA’s Kennedy Space Center in Florida on Friday, Jan. 27, 2017 on behalf of Universe Today.
It was the first disaster with a human crew and the worst day in NASA’s storied history to that point.
The tribute is named called “Ad Astra Per Aspera – A Rough Road Leads to the Stars.”

At the tribute dedication ceremony Kennedy Space Center Director and former astronaut Bob Cabana said the families of the fallen crew gave their approvals and blessing to the efforts that would at last tell the story of Apollo 1 to all generations – those who recall it and many more to young or not yet born to remember the tragedy of the early days of America’s space program.
“It’s long overdue,” said KSC center director and former astronaut Bob Cabana at the KSC dedication ceremony to family, friends and invited guests colleagues. “I’m proud of the team that created this exhibit.”
“Ultimately, this is a story of hope, because these astronauts were dreaming of the future that is unfolding today,” said Cabana. Generations of people around the world will learn who these brave astronauts were and how their legacies live on through the Apollo successes and beyond.”
The exhibit “showcases clothing, tools and models that define the men as their parents, wives and children saw them as much as how the nation viewed them.”
The main focus was to introduce the astronauts to generations who never met them and may not know much about them or the early space program, says NASA.
“This lets you now meet Gus Grissom, Ed White and Roger Chaffee as members of special families and also as members of our own family,” said NASA’s Luis Berrios, who co-led the tribute design that would eventually involve more than 100 designers, planners and builders to realize.
“You get to know some of the things that they liked to do and were inspired by. You look at the things they did and if anyone does just one of those things, it’s a lifetime accomplishment and they did all of it and more.”

The crew and the Apollo 1 command module were stacked atop the Saturn 1B rocket at Launch Complex 34 on what is now Cape Canaveral Air Force Station in Florida.
During the “plugs out” test the Saturn 1B rocket was not fueled. But the fatal flaw was the atmosphere of pure oxygen for the astronauts to breath inside the sealed Apollo 1 command module which was pressurized to 16.7 psi.

Another significantly contributing fatal flaw was the inward opening three layered hatch that took some 90 seconds to open under the best of conditions.
After working all afternoon through the practice countdown and encountering numerous problems, something went terribly awry. Without warning a flash fire erupted in the cockpit filled with 100 percent oxygen and swiftly spread uncontrollably creating huge flames licking up the side of the capsule, acrid smoke and a poisonous atmosphere that asphyxiated, burned and killed the crew.
With the scorching temperatures spiking and pressures rapidly rising in a closed system, the capsule exploded some 20 seconds after the fire started. And because of the pressure buildup inside with flames licking up the sides and the toxic atmosphere generated from burning materials, the crew succumbed and could not turn the latch to pull open the hatch against the pressure.
The pad crew tried bravely in vain to save them, fighting heavy smoke and fire and fearing that the attached launch abort system on top of the capsule would ignite and kill them all too.
An investigation would determine that the fire was likely caused by a spark from frayed wiring, perhaps originating under Grissom’s seat.
“An electrical short circuit inside the Apollo Command Module ignited the pure oxygen environment and within a matter of seconds all three Apollo 1 crewmembers perished,” NASA concluded.
NASA and contractor North American Aviation completely redesigned the capsule with major engineering changes including an atmosphere of 60 percent oxygen and 40 percent nitrogen at 5 psi blower pressure, new hatch that could open outwards in 5 seconds, removing flammable materials among many others that would make the Apollo spacecraft much safer for the upcoming journeys to the moon.
The multi-layed hatch serves as the centerpiece of the tribute exhibit. No piece of Apollo 1 has ever before been put on public display. Alongside the old hatch, the new hatch is displayed that was used on all the remaining Apollo missions.

Display cases highlights the lives and careers of the three astronauts in these NASA descriptions.
Gus Grissom was “one of NASA’s Original Seven astronauts who flew the second Mercury mission, a hunting jacket and a pair of ski boots are on display, along with a small model of the Mercury spacecraft and a model of an F-86 Sabre jet like the one he flew in the Korean War. A slide rule and engineering drafts typify his dedication to detail.”
“The small handheld maneuvering thruster that Ed White II used to steer himself outside his Gemini capsule during the first American spacewalk features prominently in the display case for the West Point graduate whose athletic prowess nearly equaled his flying acumen. An electric drill stands alongside the “zip gun,” as he called the thruster.”
“It was great to juxtaposition it with a drill which was also a tool that Ed loved to use,” Berrios said. “He had a tremendous passion for making things for his family.”
“Roger Chaffee, for whom Apollo 1 would have been his first mission into space, was an esteemed Naval aviator who became a test pilot in his drive to qualify as an astronaut later. Displayed are board games he played with his wife and kids on rare evenings free of training.”
Grissom, White and Chaffee composed NASA’s first three person crew following the one man Mercury program and two man Gemini program, that had just concluded in November 1966 with Gemini 12.
The trio had been scheduled to blastoff on February 21, 1967 on a 14 day long mission in Earth orbit to thoroughly check out the Apollo command and service modules.
Apollo 1 was to be the first launch in NASA’s Apollo moon landing program initiated by President John F. Kennedy in 1961.
Apollo 1 was planned to pave the way to the Moon so that succeeding missions would eventually “land a man on the Moon and return him safely to Earth before this decade is out” as Kennedy eloquently challenged the nation to do.

I remember seeing the first news flashes about the Apollo 1 fire on the TV as a child, as it unfolded on the then big three networks. It is indelibly marked in my mind. This new exhibit truly tells the story of these astronaut heroes vividly to those with distant memories and those with little or no knowledge of Apollo 1.

NASA pays tribute to the crews of Apollo 1 and space shuttles Challenger and Columbia
Today, Feb. 1, concludes the most somber week in NASA history as we remember the fallen astronauts who gave their lives exploring space so that others could reach to the stars – venturing further than ever before!
In the span of a week and many years apart three crews of American astronauts made the ultimate sacrifice and have perished since 1967. Heroes all ! – They believed that the exploration of space was worth risking their lives for the benefit of all mankind.

“Today we remember and give thanks for the lives and contributions of those who gave all trying to push the boundaries of human achievement. On the solemn occasion, we pause in our normal routines and remember the STS-107 Columbia crew; the STS-51L Challenger crew; the Apollo 1 crew; Mike Adams, the first in-flight fatality of the space program as he piloted the X-15 No. 3 on a research flight; and those lost in test flights and aeronautics research throughout our history,” said Bolden.
“Let us join together … in paying our respects, and honoring the memories of our dear friends. They will never be forgotten. Godspeed to every one of them.”
12 years ago today on Saturday, Feb. 1, 2003, Space Shuttle Columbia suddenly and unexpectedly disintegrated over the skies of Texas during the fiery reentry into the Earth’s atmosphere at the conclusion of the STS-107 science mission. All aboard were lost: Rick Husband, William McCool, David Brown, Laurel Clark, Kalpana Chawla, Michael Anderson, and Ilan Ramon.

Today the fallen astronauts legacy of human spaceflight lives on at NASA with the International Space Station (ISS), the development of Commercial Crew manned capsules for low Earth orbit, and the development of the Orion deep space crew exploration vehicle and SLS rocket for NASA’s ambitious plans to send ‘Human to Mars’ in the 2030s.
There are numerous memorials to the fallen crews. Among them are the tribute plaques to all five space shuttle orbiters that were the brainchild of the Space Shuttle Launch Director Mike Leinbach.
The five orbiter plaques were mounted inside the Space Shuttle Firing Room #4, above the Shuttle countdown clock at the Launch Control Center of NASA’s Kennedy Space Center.
The plaques for Columbia and Challenger, the first two shuttles built, include the crew portraits from STS-107 and STS-51L.

On this day (Jan. 27) in 1967, NASA astronauts Virgil “Gus” Grissom, Ed White and Roger Chaffee died in a pad fire inside of the Apollo 1 spacecraft that was supposed to lift off only a month hence. The tragedy shocked NASA, which was then aiming for manned landings on the moon, and caused an in-depth investigation into the spacecraft’s construction and the cause of the fire.
Above, you can see one of the first news reports after the fire took place, from ABC’s Jules Bergman and a correspondent at “Cape Kennedy” (which is called Cape Canaveral today, referring to an area adjacent to the Kennedy Space Center where the launch was supposed to take place.) “It was too late from the beginning,” Bergman said in the report, referring to the frantic effort to get the astronauts out of their burning spacecraft.
An investigation determined that a spark flew from somewhere inside of the spacecraft and easily ignited in the pure-oxygen atmosphere, fuelled by fire-friendly materials inside the spacecraft. The astronauts were unable to get out quickly because the hatch was complicated to open. The redesigned Apollo spacecraft featured a swift-to-open hatch, fewer flammable materials, covered electrical connections (to mitigate against short-circuits), and a mixed atmosphere of oxygen and nitrogen on the ground.
Safety measures arising from the tragedy did help with saving astronauts on other flights, notably Apollo 13. That mission saw an oxygen tank explode en route to the moon in April 1970.
Every year, NASA has a day of remembrance to commemorate lost crews. The Apollo 1 anniversary marks a solemn week in the agency, as it comes one day before the anniversary of the 1986 Challenger explosion that killed seven astronauts (Jan. 28) and a few days before the 2003 anniversary of the Columbia shuttle breakup, which killed another seven people (Feb. 1).
Four cosmonauts have died during spaceflight, all upon re-entry: Vladimir Komarov (during Soyuz 1 on April 24, 1967) and Georgi Dobrovolskiy, Viktor Patsayev, and Vladislav Volkov (during Soyuz 11 on June 30, 1971).

Reader Jeff Arnoldi recently approached me with an intriguing question about this Apollo 1 picture:
Note that the U.S. flag is on their right shoulders. Every other Apollo mission crew and all mission crews since then wear the flag on their left shoulders. Did the astronauts change after the Apollo 1 fire? Why did they make the change?
In response, Universe Today put a call out to several people with knowledge of those spacesuits that were used in the Apollo 1 mission, which ended fatally in January 1967 when all three crew members died in a pad fire.
A lot of redesigns were made to the equipment to prevent the same situation from happening again, but it appears the flags were not that crucial to the spacesuit design — even though a new spacesuit was used in Apollo 7.
Weeks of searching later, we have some great theories from the experts about why the flags were switched, but no definitive answer. Feel free to let us know if you have heard anything!
There’s some important historical context about the suit that we’ll get into in a moment, but first, here’s some feedback we received from a few spacesuit experts:

Walter Cunningham, Apollo 7 astronaut and backup crew member for Apollo 1:
Our crew, obviously, wore both. We were concerned about flexibility and security of the suits. We had no time to be concerned with style or decorations. I know of no policy decision on the question you asked.
Shawn McLeod, field operations manager for David Clark Co. (which constructed the suit):
Our archives indicate photos in the field of the Apollo A1-C suits both with and without the U.S. flag. Based on our literature search, our team believes positioning/placement of the U.S. flag was more than likely performed in the field after the suits were delivered from David Clark Company. Field installation of patches is not unusual – especially, for a program as fast-paced as Apollo. […]
Anecdotal evidence leads us to believe that the flags were sewn on whichever arm there was room. The left arm has a pencil pocket, and maybe with the pencils sticking out they would cover part of the flag, whereas the right arm has the neck seal pocket and a little more room. Furthermore, the referenced photo shows the flag was incorrectly positioned per U.S. Flag code. If they wanted to use a flag on the right sleeve, they would need to use the version with the field of stars facing forward. Perhaps someone noted that at some point and the correction was made.
I spoke with one of the suit technicians that supported Apollo 1 and he didn’t remember the flags being on the right arm. I have seen them in several pictures of the Apollo crew at different events, all on the right arm. Not sure at this time why and who may have sewn them on. During Apollo, we technicians would only sew the crew patches on the flight suits several weeks before launch.
I think there is a simple explanation, which is that the Apollo 1 suits were modified Gemini suits made by the David Clark Co., and the Apollo 7 suits were the first generation of [newer manufacturer] ILC suits. My guess is that two different manufacturers took two different approaches.

To learn more about this type of Apollo spacesuit, Universe Today approached Cathy Lewis — a curator who specializes in spacesuits at the Smithsonian National Air and Space Museum.
Intriguingly, it appears every NASA spacesuit that has a flag on it — besides the A1-C used in Apollo 1 — has its flag on the left. More from Lewis:
In all other suits in our collection where a flag is present, the flag is on the left. The collection includes suits made for NASA for programs and those made as prototypes and suits made for the USAF [United States Air Force] for the Manned Orbiting Laboratory program. Just as a note there were no flags in the Mercury suits that B.F. Goodrich made for NASA.
As the Bill Nye: The Science Guy show used to repeat … but wait, there’s more.
Lewis also gave us some great background on the suits used for Gemini and Apollo. The Apollo missions actually had two different sets of pressure garments — the A1-C and the A7-L, while the Gemini missions used the G4-Cs. Essentially, the G4-C and A1-C suits were the same thing (a high-altitude suit design adapted for space), made by the same prime manufacturer — David Clark Co. The next set of suits, the A7-L (made exclusively for space work), had ILC Dover as the prime manufacturer.
Lewis added that she does not see the flag switch as being tied to the change in manufacturer.

Lewis did a great job summarizing a lot of history in a few paragraphs, so we decided to include her entire e-mail here.
It is not likely to have anything to do with the manufacturers per se, because, DCC had placed the flag on the left shoulder for the Gemini program. The shift between DCC and ILC is a very long and complex story that began in 1962 with the first solicitations for suit prototypes for the Apollo program. ILC was selected as the suit manufacturer in 1965 with Hamilton Standard as the primary contractor by virtue of their government contracting and systems engineering experience.
That corporate relationship fizzled and left NASA with the option of putting off the design of the Moon-walking suits and falling back on their Earth orbital experience with DCC and Gemini for the early, Earth-orbiting Block I missions.
While DCC was making A1-C suits based on the G4-Cs that Ed White had used for the first US spacewalk, they were also competing with ILC, HS and others for the new Moon-walking suit contract.
The 1967 Apollo 204 fire changed NASA’s plans for different Block I and Block II (lunar orbiting and lunar landing) spacesuits. The resulting contract went again to ILC as primary with HS [Hamilton Standard] as sub with responsibility for the life support systems and systems integration for a suit that worked in Earth and lunar orbit and moon-walking.
Unless I am missing something, I don’t see an engineering issue over the placement of the flag.

In remembrance of the Challenger accident 25 years ago today, several notable people have issued statements in memory of the Challenger crew, as well as the crews of Apollo 1 and Columbia. Below are a few; add your own, if you like, in the comments section.
Additionally, a high-quality documentary about the accident has been produced by SnagFilms, an online library of more than 2000 documentary films available to view for free. The film, which you can access below, is called “Catastrophic Failure.”
Statement by Steven J. McAuliffe on the 25th Anniversary of the Challenger Accident
“That people across the country steadfastly remember the crew members of Challenger is both comforting and inspirational to our family. Scott, Caroline and I very much appreciate the kind thoughts and continuous support we have received over the years.
Christa confidently and joyfully embraced life, no less than her friends and colleagues on Challenger, and no less than the crews of Columbia , Apollo 1, and all of those people who courageously follow their own paths every day. I know Christa would say that that is the most precious lesson – ordinary people can make extraordinary contributions when they remain true to themselves and enthusiastically pursue their own dreams wherever they may lead. Our family knows that generations of students and teachers will continue to share her love of learning and love of life, and will do great things for our world. We believe Christa would be especially pleased by, and proud of the Challenger Center for Space Science Education and its mission. The Challenger Center honors each crew member’s devotion to learning and exploration, touching the lives of over 400,000 students and 40,000 teachers each year. In that way, Challenger Center continues the teaching mission of all the crew members of STS-51-L.”

US President Barack Obama on NASA’s Day of Remembrance (January 27, 2011)
“Fifty years ago, a young President facing mounting pressure at home propelled a fledgling space agency on a bold, new course that would push the frontiers of exploration to new heights. Today, on this Day of Remembrance when NASA reflects on the mighty sacrifices made to push those frontiers, America’s space agency is working to achieve even greater goals. NASA’s new 21st Century course will foster new industries that create jobs, pioneer technology innovation, and inspire a new generation of explorers through education – all while continuing its fundamental missions of exploring our home planet and the cosmos.
Throughout history, however, we have seen that achieving great things sometimes comes at great cost and we mourn the brave astronauts who made the ultimate sacrifice in support of NASA missions throughout the agency’s storied history. We pause to reflect on the tragic loss of the Apollo 1 crew, those who boarded the space shuttle Challenger in search of a brighter future, and the brave souls who perished on the space shuttle Columbia.
Though triumph and tragedy, each of us has benefited from their courage and devotion, and we honor their memory by dedicating ourselves to a better tomorrow. Despite the challenges before us today, let us commit ourselves and continue their valiant journey toward a more vibrant and secure future.”

Message from NASA Administrator Charlie Bolden: Day of Remembrance
“The last week of January every year brings us the opportunity to reflect on the sobering realities of our space exploration enterprise. Each time men and women board a spacecraft, their actions carry great risk along with the opportunity for great discoveries and the chance to push the envelope of our human achievement. Today, we honor the Apollo 1, Challenger and Columbia crews, as well as other members of the NASA family who lost their lives supporting NASA’s mission of exploration. We thank them and their families for their extraordinary sacrifices in the service of our nation.
This year marks the 25th anniversary of the loss of Challenger — a tragedy that caused us to completely re-think our systems and processes as we worked to make the shuttle safer. The nation will never forget Jan. 28, 1986, nor its indelible images. The astronauts in that crew were personal friends of mine, as were the astronauts aboard Columbia when it was lost. The Apollo I crew perished while I was studying at the Naval Academy, and I mourned their loss in the line of duty with the nation. These brave men and women will always be a part of us, and we are still building on their legacies.
NASA has learned hard lessons from each of our tragedies, and they are lessons that we will continue to keep at the forefront of our work as we continuously strive for a culture of safety that will help us avoid our past mistakes and heed warnings while corrective measures are possible. In memory of our colleagues, I ask the NASA Family once again to always make its opinions known and to be unafraid to speak up to those in authority, so that safety can always be our guiding principle and the sacrifices of our friends and colleagues will not be in vain.
On this Day of Remembrance, as we honor our fallen heroes with tributes and public ceremonies, I will take part in a wreath-laying ceremony at Arlington National Cemetery. Across the country, flags at NASA Headquarters and the NASA centers will be flown at half-mast in memory of our colleagues lost in the cause of exploration.
The legacy of those who have perished is present every day in our work and inspires generations of new space explorers. Every day, with each new challenge we overcome and every discovery we make, we honor these remarkable men and women. Please join me in working to fulfill their dreams for the future.”

“Far better is it to dare mighty things, to win glorious triumphs, even though checkered by failure than to rank with those poor spirits who neither enjoy much nor suffer much, because they live in a gray twilight that knows not victory nor defeat.” – Theodore Roosevelt
It’s hard to chronicle any of the Apollo flights without mentioning the Apollo 1 fire. And while many believe the Apollo program perhaps wouldn’t have succeeded without that disaster, the sacrifice made by Gus Grissom, Ed White and Roger Chaffee definitely saved the crew of Apollo 13.
“Among the early space missions, I’ve always believed that the greatest courage was needed by their first crews,” said Apollo engineer Jerry Woodfill. “Whether it was Al Shepard, the Apollo 1 crew, or shuttle astronauts John Young or Bob Crippen, the most likely danger would be the first time any new space craft was launched into space. Flaws in design or manufacture could very well be fatal during maiden missions.” The crew of Apollo 1: Gus Grissom, Ed White and Roger Chaffee. Credit: NASA
On January 27, 1967, during a test on the launch pad with the crew on board, tragedy struck when a flash fire started in the command module. With the pure oxygen environment inside the capsule, the fire quickly proved fatal for the crew before they or workers at the launch pad could get the hatch open. Although the ignition source of the fire was never conclusively identified, the astronauts’ deaths were attributed to a wide range of design and construction flaws in the early Apollo Command Module. The manned phase of the project was delayed for twenty months while these problems were fixed.
“To suggest the dire event of losing three brave astronauts contributing to Apollo 13’s rescue seems almost ludicrous,” said Woodfill, “but the evidence is striking. What Grissom, White and Chaffee contributed to the rescue of Apollo 13 makes them even more heroic than they were when they gave their lives so that men could go to the moon.”
The irony of the whole situation involves the hatch. Following Gus Grissom’s near fatal drowning when his Mercury capsule sank, the Apollo hatch had been redesigned to avoid the kind of unexpected actuation thought to have caused Grissom’s “Liberty Bell 7” to sink.

“Unfortunately, it led to a hatch impossible to open before the Apollo 1 crew expired,” said Woodfill. “Nevertheless, circumstances used Gus, Ed, and Roger’s sacrifice to save other crews in route to the Moon.”
NASA fire-proofed all future Apollo vehicles with non-flammable materials, used a pad atmosphere of a nitrogen/oxygen mix, and coated of all electrical connections to avoid short-circuits.
“Every switch contact and wire was coated with a moisture proofing substance called conformal coating,” said Woodfill. “Were it not for fire-proofing the Apollo command and service modules, Apollo 13, likely, could not have survived reentry. The cold, damp reentry module interior faced extreme condensation of water vapor from the astronauts’ breath.

Woodfill said when Apollo 13’s switches were activated for reentry, the interior would surely have burst into flame, were it not for the fireproofing. Condensed water droplets might have short-circuited panel switches, circuit breakers, and connector wiring.
Woodfill said America might never have landed a man on the Moon without Apollo 1. If a fire had occurred on the way to the Moon, it might have ended the will to land men there. “Imagine the horror of the world at such an event,” said Woodfill, “hearing the crew’s painful cries from deep space, ‘We’ve got a fire in the spacecraft.’”
Apollo 1 and the fireproofing of future Apollo spacecraft prevented such an event.
A favorite quote of many managers of the Apollo program, Woodfill said, is from President Theodore Roosevelt, the one posted at the top of this article.
“In a sense, the Apollo One mission was altogether different from Challenger, Columbia, and Apollo 13,” said Woodfill. “No one had dared such a mighty thing as to man the first Apollo spacecraft into orbit. And it, in this case, was fraught with suffering, failure and defeat, rather than a glorious triumph and victory.”
But later, it allowed for great triumph with the success of the Apollo program, and a defying of the odds of the Apollo 13 crew’s survival.
