The F-105 earned the nickname Thud after the character Chief Thunderthud on the Howdy
Doody TV show. The main mission of the F-105G was the detection and destruction of North
Vietnamese SAMs that would then allow other aircraft to safely carry out their assignments. In
order for the F-105Gs to do this they were always “First In Last Out” and piloted by volunteers.
The F-105 was the only U.S. aircraft withdrawn from combat due to high losses. Having flown
20,000 sorties over Vietnam 382 of the 833 F-105s produced were lost.


On April 19, 1967 Major Thorsness and Captain Johnson flew their F-105F Thunderchief 63-8301
along with their wingmen on a mission to destroy surface-to-air missile sites. They destroyed their
first objective and attacking the second SAM the wingman was hit by ground fire and the crew
bailed out. 63-8301 circled the parachutes to be able to give SAR their location. They spotted a
MiG-17 and destroyed it. Low on fuel Thorsness began to leave but returned to take on four MiG-
17s, destroying one while the other three fled.
