As for the "nothing to show for it but ever spiffier computer graphics", what about the currently built heat exchanger module, the tested heat exchanger, the tested rocket engines, the tested modified jet engine being used to test the precooler, the experimental turbine, the wind tunnel to test frost formation with the hydrogen in the heat exchanger, and a host of other hardware that has been built to test various aspects of the system? Hardly just computer graphics are they?
Note, this time, I must declare an interest here. I work for Reaction Engines on the ED nozzled rocket engine test programme, so I do know what hardware exists, and in fact the reason I am late replying to this thread is due to being at static test firings this week.
Mr Lyons, do you ever check your facts before your usual negative comments on various rocketry ventures around the world?
