I retired with only having had to get a few stitches here and there and the accompaning tetanus shot and I consider myself very fortunate.
Saw a guy lose a finger once because he was wea ring in the shop and got it caught on engine hardware he was going down a ladder....all his weight was going down and it snapped before knew it.....fracture was so bad they amputated.
Bad juju
Was in a KC-135 hellhole working on a servo motor. The stab trim wheel was locked and tagged out - a Red X in the forms.
A crew chief REMOVED it and started to move the wheel manually. We got out of there damn quick, ripped pants and all.
My co-worker started to scream at the guy, an NCO. That crew chief lost his plane because of that. Think he got other one back in a few months, but he completely disregarded the safety gear in place. Was told he got a Letter of Reprimand.
