But I bet this would be twice risky as the Concorde. I'd never ever try to put my life at that risk level even if someone would offer me ride for free.

This is not the orbital version, which is called Skylon and uses an engine called Sabre. Just for the record: Reaction Engines is the company founded by Alan Bond, who designed HOTOL.

Any 5 year old can draw a picture of a blimp-like plane, put hydrogen engines on it and say it can enter low orbit....at mach 5 thats simply a lie.

Call Chrysler and tell them to lay off the design department because the new design for mini vans in 2035 will be the retro 94' caravan look. I agree with ZEKE.

This should be available about the same time as the Jetson's flying cars. The publicists could have at least had the courtesy to credit an old ('60's) Russian supersonic bomber design.

Now look guys - We have all seen the failure of "single-stage-to-orbit" designs in the recent past - for example X-33 efforts. Single stage to orbit is not easy and currently beyond material (weight/strength) and propulsion capability - We must await REAL technology breakthroughs before such designs make sense! Physics loves Staging!! Oh and something else –
