Just wondering if the planes will exibit wingtip contrails under moderate-high G-load. Pappy Boyington talked about this in his book, as he looked down from 20 some thousand feet, he saw dozens of little white streaks, like chicken claw marks in the sky,caused by wingtip contrails during the dogfights, and he wished 'that everyone could see this sight.'

Well, lots more people can, if its put into this sim! http://ubbxforums.ubi.com/images/smiley/16x16_smiley-happy.gif

No question about it. Maybe.

Actually any aircraft in a humid enough environment will leave wingtip contrails, even under normal approach conditions. At higher angles of attack in high humidity the whole upper wing surface will "fog", you can probably see this at your local airport watch'n the jets takeoff on a rainy day.

This effect is in FB, is it not? You can see contrails from the wingtips now.

Indeed they are already modeled in FB and is one of the ways you can tell you are getting close to stall. They are not persistent like the contrails that form at high altitude from engine exhaust, but they are readily visible. Humidity does have a direct bearing on their formation and conditions in the PTO, where Boyington was when he saw them, were likely hot and humid. I live in Florida and used to work at NAS Pensacola, the "Home of the Blue Angels", and during their practices the vapor would readily condense off the wingtips, be highly visible in the engine intakes and sometimes almost obscure the entire upper surface of the wings in a hard maneuver.
