Capt Dufresne launches off a Genie training rocket (ATR-2A) during William Tell 1982.

Dufresne's aircraft for the Meet, s/n 56-0457, is pictured taxing armed with a M61 "Six Shooter" gunpod. On the opening days of the competition Dufresne scored the first gun hit  against a Low Cost Towed Target (LCTT), he was able to hit the target in less than 58 seconds from the "clear to fire call".

F-106A 59-0057's crew, Pilot Capt Dufresne and Crew Chief SSgt. Michael J. Crowder pose with their F-106 interceptor during William Tell 82.

The then Capt Dufresne is pictured in front of Det 1, 318th FIS HQ at Castle AFB CA .

Capt Dufresne assumed command of Det-1 318 FIS in a formal ceremony where the detachment flag was passed on by 318 FIS Commander Lt Col Gordie Breault.

F-15's 76-0071 & 76-0098 fly over San Francisco's Golden Gate Bridge during a flight from Det 1, 318th FIS alert site. Aircraft and pilots were rotated periodically between McChord AFB and Castle AFB, but maintenance of the aircraft was performed by personnel assigned directly to the detachment.

A newly promoted Maj Dufresne is pictured with his name freshly stenciled on his F-15C s/n 80-0048 while at his next assignment with the 57th Fighter-Interceptor Squadron, Keflavik NAS, Iceland. 

F-15C 80-0048 sails over Blafjöll mountains on 5. May 1986. The 57th FIS carried conformed fuel tanks to give their Eagles additional range in the barren Icelandic landscape.

A common sight during the Cold War, pilots of the 57th FIS "Black Knights" intercepted over 3,000 Soviet aircraft between 1962 and 1991,  Dufresne himself was involved in intercepting 22  Russian Tupolev Tu-95 Bear "D"  &  Bear "F " Maritime reconnaissance/anti-submarine warfare aircraft.
