A fine pictorial study in black and white photographs not only of ""what Colonel Glenn did all day"", but of his training, earlier space flights, the special equipment developed for space, and the aftermath of a successful flight. February 20th, 1962 highlights the story however. Pictures of Glenn's pre-dawn preparation, the launching, the sights photographed in flight, the recovery of the space capsule and Glenn's de-briefing at Grand Turk Island will recall the day to all readers. Interesting too, are the excerpts of radio conversations between Glenn and Cape Canaveral. By no means a comprehensive study of space travel, this is for the layman who would like a memento of the historic journey.
