OK...
...it looks like one of the Hiryu Zeroes returning from the second strike ditched and its pilot was recovered; that's one less aviator loss. I'm just reading and skimming in between work, play, pleasure and life here; but Lundstrom is as helpful as Shattered Sword.
In addition to a shortage of airframes--the Kate line was even reopened for a time when Nakajima's Jill ran into production startup problems--the Japanese had ordnance supply problems as well. That's one reason why Lexington was attacked off Rabaul with bomb-toting Betties rather than torpedo carrying birds.
And while the United States had many problems with aircraft availability (Hornet left the West Coast with only some 65 carrier aircraft)--Saratoga's torpedoing in early '42 released many aircraft which then filled out operational squadrons--as well as with supplies of self-sealing tanks, armor and the like, the Japanese had nothing like the industrial base to handle the needs of the Pacific War.
