Stretching the truth. Yeah, Mercury astronaut John Glenn selected Tang for its 1962 orbital flight. It was also used during some Gemini flights (Aldrin said recently he hated it), but by the time the Apollo missions started it was no longer in the astronauts’ menu. The Apollo crews drank indeed artificially orange-flavored ( other fruits also) drinks, but those was made specifically by NASA.
Neat publicity, from another era.
