I saw him give a little speech at a Northrop family day revealing the B-2. Or maybe it was just a family day in Palmdale, too many years ago. It gave me a thrill, although I'm not too sure the family understood what he represented. It always amazes me how much trouble they had going through the "sound barrier" when now planes do it effortlessly. You had to be careful flying number two in extend trail formation performing a loop, basically chasing lead, in the T-38 as it was easy to go supersonic . That was a no-no. The only thing you noticed going supersonic was a dip in the air speed indicator.
