I was in the 333rd TFS as a Wild Weasel Bear from Nov 1968 to Jul 1969. In early months of 1969 there was a F-105D that crashed on the take off end of the runway near the overrun/runway lights. The pilot was a Major Pepe' Martin. He was badly burned and was medevac to Yokota AB Japan where he died. I don't know if this is the incident you are referring to or not.
