So if mirrors are usless why can you google fighter cockpits and come back with modern jets with several big mirrors inside of the cockpit. If it's a cockpit with a REO even he has at least one mirror. You google for ww2 cockpits you see some have them some don't. Some inside the cockpit some out side. One ETO P51 squad disicovered if they mounted the outside mirror farther out from the canopy frame it greatly reduced the vibration and they mounted a top, left and right side mirror.
I found F4f, F6f and F4u with the mirror(s) mounted inside of the canopy frame usualy inside of the leading edge frame of the movable section. A few F4f and F6f with it mounted inside in the top of the windscreen. The F4u-1 with a a bulge in the panel just above the pilots head with a mirror in it. The F4u-xx with two, one on each side of the leading edge frame of the movable bubble. I got F4 Phantom hits serching for the F4f and some had interior mirrors.
The bulge is there on U.S. F4u-1. This is a good close up photo. Ever noticed in the game our F4u-1 is modeled in that regard incorrectly.

English fighter pictures show many with mirrors and many without from the ETO to the PTO and in between.
Found non-standard mirrors on P40's and none on\in P39. Some P38 do some don't. Bong used one. Germany, Italy, Japan and Russia didn't seem to use them in their fighters.
So thats alot of guys opting to use them from 1938-present.
Maybe we go with Hitech saying the codeing he could put together would give a minority of players with high end machines an advantage. Then my question: can it be given to all machines running the game but, with low quality graphics in the mirror. Or is it only some high end machines would be able to make use of it at this time.
