usaf markings

Hey you guys,
I’m working on a book describing in detail the marking history of USAF fighters. For that I’m looking for detailed shots of tail markings of all USAF TAC or ACC aircraft.
If there is anybody who can help me with pics or info on tail markings of USAF F-16s and F-15s please mail them to [email]usafmarkings@yahoo.co.uk[/email]

Thanks very much
