Not proving the point one way or the other, but some thoughts from Geoff Fisken, the top Buffalo ace outside Finland (FlyPast, 2006):
"In order to be succesful aginst the Japanese, especially the 'Zero', one had to have an altitude and attitude advantage. I thought the Buffalo was a delight to fly. A beautiful aircraft but a bit underpowered. The 'Zeros' were too fast and they could turn inside of us. If you wanted to dogfight them, you simply committed suicide.
Being young and and somewhat foolhardy, I still had aspirations of growing old back in New Zealand. When we saw a flight of Japanese fighters coming in, we climbed as high as we could above them. As they drew closer, we pushed the old Buffalo over, throttles to the stops and went screaming down, firing through them. We were always outnumbered, which to me was an advantage as I had more targets to pick from. On February 1, 1942, it was no different. I already had five victories against various Japanese aircraft. Little did in know that this woud be my last fight in the Buffalo.
Pushing the nose over and picking up speed, I hurtled myself at the swarm of 'Zeros' below. I picked one out and gave him a three-second burst. With no protective armour, it burst into flames and cartwheeled down.
Two of his friends latched into me and as I tried to shake them, I got a bit of a cannon shell in the leg and a bullet into my arm. The Buffalo was chewed to pieces as I dove for the deck. My undecarriage was shot out. My engine was coughing and smoking as my prop stopped. I managed to bring it in to Kallang, and crash-landed in there. In the process, I busted up my knee, but other than that I was all right.
In late 1943, the injuries that I received in Singapore began to catch up my body. Reluctantly, I was invalided out of the war and returned to New Zealand. I picked up where I left off, working as a shepherd on one of my family's stations."
