or we’ve never been to the moon which would explain why we haven’t been back....don’t you know that technology goes backward?....that what was apparently accomplished 50 yrs ago is just too hard to do today....
The real explanation is quite simple. Concorde lost money every time it flew, and eventually British Airways & Air France tired of writing the big checks needed to keep it in the air.
Apollo cost half a billion for every flight, not counting development cost. Congress stopped appropriating the money to pay those bills. No bucks, no Buck Roger's. Very simple.
