Well.. it's a fact walkin the flightline kept me in shape.
With my T.O., my field jacket, my tool box, and whatever box I needed to R&R, along with any test gear I needed.
Usually I dragged a new guy just outta tech school along to help carry and mebbe teach a bit.
Usually.
Enough to stand on my head in an F4 cockpit and fish out the screw my Airman no-sense dropped under that Martin Baker Ejection seat.
I started puttin on weight when I got stuck on a desk for majority of my days.. dint happen till I was in my 30's tho, and was a major factor in deciding not to stay in any longer .. I dint join USAF to answer phones, yanno?
