Narrative:
Crashed after mid-air collision with an Aero Commander 690A (N40MP) on November 12, 1974 at 18:04 MST 180 NM Northeast of Nellis AFB. Wreckage pattern approx. 2 NM long, impacted 8 NM NW of Kingston Utah.

Sigma flight (2 x F-111A of 428th TFS) were joining KC-135A (tail number 58-110 callsign Toft 51 from Grand Forks 319th BW). 67-055's call sign was "Sigma 71". The other F-111A involved, 66-058 call sign "Sigma 72", returned to Nellis AFB unscathed.
Both crew of 67-0055 - Captain Peter Granger (33) of Fargo, ND and Captain Paul B. Sperry (27) of Palo Alto, Calif. - ejected safely
The Aero Commander N40MP (from Butte, Montana), belonging to Montana Power Company, also crashed, killing the pilot [later named as Rocco B. Fiori, 34, of Butte, Montana].
The KC-135 observed the collision and fireball from 22 nm away. According to the NTSB report, the F-111A, being the faster aircraft, collided with the Aero Commander 690A at a very shallow angle (approx 0-10 degrees) when it misidentified the Aero Commander 690A as being the KC-135 tanker they were to rendezvous with. The F-111A overtook N40MP from the rear.

The National Transportation Safety Board determines that the probable cause of this accident was the F-111A pilot's misidentification of the Turbo Commander as a refueling tanker with which he intended to rendezvous.
Contributing to the misidentification was his failure to use prescribed procedures and techniques during rendezvous with a tanker aircraft for refueling.
