(04/08/1969) -- The May 18 launch date for the Apollo 10 mission is now little more than a month away for its prime crew, shown here at Complex 39's Pad B. From left are Thomas P. Stafford, commander; John W. Young, command module pilot; and Eugene A. Cernan, lunar module pilot. Visible through the girders of the Mobile Service Structure is the launch vehicle which will hurl them toward the Moon in a mission that is to carry Stafford and Cernan to within 50,000 feet of the lunar surface.
