I watched an interesting show where the TV guy barely pushed on the metal and you could see it bending in. Apparently you could do this almost everywhere on the vehicle. For that reason the crews were not allowed to push anywhere to move the vehicles around. There were charts and manuals for what was allowed.

Yes, this is the Mitsubishi A6M Zero fighter from WWII. This, and many other reasons, meant the Zero was so light it had an incredible range and was highly manueverable. the downside was there was no pilot protection and one hit from an incendiary .50 cal round would cause the plane to explode in a blaze.

It would have cost Mitsubishi 350 lbs to have self sealing gas tanks and an armored tub for the pilot. The engine in the Zero, very lightly stressed and capable of much more, was only producing 950hp when Western radials were cranking out 1700hp or more. Japan, like Germany, flew their best pilots until they were killed. In Japan's case it was ridiculous they thought so poorly of their aviators. BTW, the Japanese training program for pilots was among the most rigorous and best there was.
