Skylab mission numbering

[GordonD]

In today's Ups and Downs entry I refer to the fact that Skylab 4, the third manned mission, had the numeral '3' on its mission patch. It was the third manned expedition but the launch of the workshop itself had been designated 'Skylab 1'. Here's a link to the website of the late Bill Pogue, who flew on Skylab 4 (or was it 3?) explaining how this mix-up came about,.
