I know I am probably asking the impossible but I could use some help.I am trying to identify the F4 Phantom pictured in this crash for historical reference.I need to be able to identify the "Tailcode".It should be FA,FO,FG,FP,FY or SJ followed by a three digit number.For example FG 123.This photo was taken at Ubon Airbase in Thailand during the 1960's or 70's.The tailcode info will enable us to be accurate in determining just when.Your help will be greatly appreciated
