I too like to remember those who have given the ultimate sacrifice in the quest for scientific achievement, but I have no desire to go look at the coffin. I'd rather watch a nice Imax movie of a shuttle floating over the horizon.
Plenty of sacrifice went on before the shuttle came into the picture. The original JFK space program never included a really big gas can with a glider strapped to it. Interesting idea if not an excellent engineering feat but it never included efficiency so it had to carry a lot of fuel to get up there on a fully automated launch and structurally was only designed for a glide style descent into the atmosphere which didn't give a lot of choices in landing it. JFK's short list guys was better.
