Well then, thank you for your service.
DynaSoar was the correct design (USAF) for a LEO vehicle, but it was not the way to go for manned space exploration - something their was really no political will to do in the first place. Had the premise of manned space exploration beyond LEO been true, Orion and later NERVA would have been fully funded. We would have been (under Orion) on Mars in 65, and Venus by 74.
You still have no clue why manned space exploration is of extreme importance to our national defense. And I’m sure nothing said will change your mind. But unless America finds the political will to go beyond LEO, the US is finished and the long retreat begins. And ends in dusty villages, ruined cities, wide-spread Third World poverty and hunger.
'is' is not 'was.' The Apollo project was, like the non-existent missile gap, political. And stepping on the Moon was not space exploration. A gradualist approach to space exploration would have been more valuable and less expensive.
