I think we had a pretty good success rate in my class - a couple of guys had to repeat it because they took longer than the hour alloted to complete the swim. Now, to be fair, you had to be athletic to even get into the Navy flight training program. You had to meet minimum requirements for a 1.5 mile run, pushups, pull-ups and sit-ups. The recruiters warned you that there would be lots of swimming as well.Astro, out of curiosity what was the success rate of the mile long swim in full gear? Were there any time restrictions? That had to be an absolute bear!
One friend of mine, an AOCS classmate, was a “swim rock”. A former football player at Tennessee Tech, he just couldn’t relax in the water. He would tense up and sink like a rock. He failed the drown-proofing over and over. He had to attend lots of remedial swim classes, but eventually made it. He was smart, determined, and a very competitive athlete, but not a great swimmer. Barry Eugene Wilmore.
The world knows him now as the astronaut - former space shuttle pilot, International Space Station Commander, and part of the crew that was accidentally stranded in space for 9 months by the Boeing Starliner test flight.
But back in 1986, Barry was a classmate who needed help meeting the swim standards.
