I noted mention of two things about the Zero, earlier in the thread, those being wing flutter and a limit of 5Gs on pull-outs from dives. They both tie into a report I read, sometime back, of a Zero which was being tested by the Americans. I want to say it was the "Akutan Zero," but it may have been one captured later in the war. Given the report was going to have some anti-Japanese bias almost as a matter of course, a couple things still stood out for me. I'm working from memory here, but I think I remember it fairly well.
The "wing flutter" was mentioned as "wingtip warping." It was said that, in any turns approaching 6Gs, the tips of the wings would begin to bend. If the G forces weren't reduced, the conclusion was the wings would rip themselves off. This would explain the "squared-off corners" in the maneuver described earlier in the thread, short moments of higher Gs, which could not be sustained.
In an interview video I watched with an American WWII naval pilot, the pilot bluntly stated that, at 6Gs, a Zero's wings would come off. That would go a long way toward explaining "Swede" Vejtasa being able to out dogfight three zeroes while flying a Dauntless, which was featured in the "Dogfights" TV series episode "Long Odds." Due to the facts 1) the Dauntless had such structural strength, and 2) Swede was able to pull higher Gs as a trained divebomber pilot, he was able to get his plane around 180 degrees each time, and still have time to build up some speed, before the Japanese pilots could swing around for their next pass.
Overall, I found the article accurate in some places and lacking in others. I do agree the Zero was never a super plane, even though it somewhat seemed like it when the war started. The "rookie" American pilots flying Wildcats had a positive kill ratio over the Zero, from the beginning of the war. By the end of 1942, that ratio (Wildcat vs Zero) was claimed to be almost six to one in favor of the Americans. Even taking exaggerated kill claims into account, it was still pretty grim for the Zero. It only got worse for them from there on.
