I've now met several, and they've all been a real treat. Charlie Duke, Ken Mattingley, Jim Lovell, Fred Haise, Al Worden, Alan Bean, Tom Stafford, Eileen Collins, Scott Altman, and more.
In some sense they are very similar, and they all give credit to the men and women on the ground who made it happen. But they really do make it happen, and are amazing people.
Among them, Bruce McCandless was one of the best - an absolute gentleman, a brilliant speaker, and fascinating.
I'm sorry to see that he has passed from us.
