Show Summary Details

Quick Reference

‘Very OK’ or ‘Great’. John ‘Shorty’ Powers, NASA's public-relations officer, introduced the term by misquoting astronaut Alan Shepard during the first sub-orbital flight in May 1961. Powers soon discovered that Shepard had only voiced an enthusiastic ‘OK!’, but the press had already popularized the expression.
