Mike, just come to warbirds at the first of the week, and meet some folks, and ask politely. Best to come early in the morning when the flight line is open and pilots are not busy with the briefing for the show. If you meet me, I can introduce you to some of the folks, but really don't need me. Now don't have a thin skin, you may ask 5 people and get 3 no's, but just persist politely. I used to go every year to the ultralight area and beg/bargain for a ride. Got some No s, but got a ride almost every year.
I don't have a warbird there this year, or you would be welcome to use mine.
As for models, there is a famous warbird calender , based I think in Dallas with some great looking girls in the Vargas style and with warbirds.
I don't know of any pilots that don't like ladies, but I can't speak for all these jet guys who ride around in air conditioned cockpits. To each his own. And pilots/owners almost always like to have good photos of their planes, and sometimes are too busy to take em themselves.
If you were using my plane, I'd have to supervise and the less clothes the model wears the closer I'd have to supervise to make sure she doesn't hit any sharp or hot parts.
We just had a 1930s/1940s style dance at Boulder airport with many people in vintage costumes, some of which were pretty small. There were lots of photos taken of girls up on the wing of a twin Beech, etc, and everyone had a good time. In 32 years of being around warbirds I have never heard or seen of anyone objecting to sharp ladies being photographed with hot planes. As far as using a F-16 rather than something classic, that is a matter of taste.
