This was copied from the crash report:
On 9/1/78, F-105F serial number 63-8263 was scheduled to fly a BFM sortie as lead of a two aircraft formation. Crew briefing, engine start, taxi and “end of runway” were normal. Takeoff was at 3:43pm PDT. Flight to George AFB working area was normal. During the first BFM engagement the centerline tank departed the aircraft. The aircraft went out of control and both crew members ejected. The aircraft crashed and was destroyed. Both crew members, Captain Eddie M. Graham and Captain Frank S. Hartman received major injuries.
After spotting some of the wreckage from above last weekend, Tom and I returned to try and reach the crash site from below.
