Columbia launched on schedule from Kennedy Space Center (KSC) at 7:19 am EST, 11 November 1982. The shuttle carried a crew of four – the largest spacecraft crew up to that time – and the first two commercial communications satellites to be flown aboard a shuttle. A planned spacewalk by Lenoir and Allen, the first of the Space Shuttle program, was postponed by one day after Lenoir became ill, and then had to be cancelled when the two spacesuits that were to be used developed problems.
