Lachlan "Mac" Macleay (born June 13, 1931) is a retired colonel in the United States Air Force and a former USAF astronaut. Although he trained for the USAF Manned Orbital Laboratory (MOL), the program was cancelled before any of the MOL crews reached space. The MOL program was not as memorable to me as the friends I made there. I got to be around some of the smartest and most dedicated people in the world, and I wouldn't trade that for anything. — Macleay, describing his MOL experience.
