My God! What a shot! It's all so marvelously blue! The gradients of the plane and the vignetting of the photo with the surreal placement of the moon all come together to really impress me. Tell me you have a print of this. You do, right? And you're showing it to everyone who will look? Because you should be, you deserve attention for this!
Very nice. It is tough to shoot through plexiglass and it's not surprise you went through so many frames before you found a keeper.
In all honesty though, you guys should really check out some of the stuff at www.airliners.net. (This isn't to disregard your pic, JerBoyd, which is pretty cool). But if you dig these shots, look at some of the stuff on that site!
(That's just shots with the moon - there's some insane stuff on there and it's easy to spend a few hours looking at photos).. Great spotters (airliner photographers) forum on there too with people discussing technique, airports to shoot at, crazy long telephoto lenses, etc..
