Money well spent on space programme after all we got non stick frying pans out of it. Just think how many Brillo pads we would have got through without the invention.
Actually teflon was invented in the 1950s & whilst used by NASA for rocket nose cones etc it was not invented by them. But Pasta is correct, the benefits of Apollo far outweighed the costs, even if you ignore the sheer achievement of putting men on the Moon.
