Thanks for all the welcomes. I stumbled here as a result of Google bringing the article--ShadowSpear Special Operations - Special Operators Take on MFF School—to my attention.
As the article discloses use of instructors providing “one-on-one instruction up through jump 13” I thought I’d give a little bit of history of the 23rd AF MTT which qualified all members as military freefall parachutists from about November 1984 to about December 1986.
This course was to my knowledge was the first military free fall course to use accelerated free fall methods of instruction. The 23rd AFF MTT course were certified and approved under by the US Army John F. Kennedy Special Warfare Center and School. The individual at JFKSWC that certified the course was John McDermett-MFI-123.
To my knowledge however none of the 23 AF MTT instructors were given MFFI numbers.
My MFF #4220, issued 20 January 1985 was signed off by Chief Instructor Captain Joseph A. Andrzejewski. I guess I better scan and send in my DD-214 for further verification purposes.
