And before anyone gets carried away with the disaster looking for a place to happen of 40% of men in the YAG designated as Naval Aviators AFTER December 1940, note that -
VB-5 had 24 aviators, 15 of whom were designated on or before December 1940, 9 of whom after and two of them had 5 months MOB. The squadron had only 18 aircraft.
VS-5 had 25 aviators, 13 of whom were designated on or before December 1940, 12 of whom after, eight of them had at least 6 MOB. Just like VB-5, only 18 aircraft.
VT-5 had 11 aviators, 9 of whom had been designated on or before December 1940, 2 of whom after, except one of them was a former NAP and, obvious from his MOB pretty long serving. Without bothering to look it up I believe VT-5 had but 10 serviceable TBD at the time of this report. (In those days an NAP accepting a warrant or a commission had to be checked and designated as a Naval Aviator and no longer a Naval Aviation Pilot . . . a legal quibble, nothing to do with whether or not one can fly, but everything to do with one's legal status.)
VF-42 had 19 aviators, 14 of whom were designated on or before December 1940, 5 of whom after, two of them had been with the squadron as AvCads and their DORs reflect back dating to their completion of flight training, thus being in the squadron for about a year each, and, just like the SBD squadrons, only 18 aircraft.
Kind of stuff a commander has to think about, especially the first time his squadron goes into action. I'll let someone else figure out who flew what mission, but how many short term ensigns do we suppose got left on the ship during strikes?
