TSA agents would have a fit with things I've carried on board planes back in the 80s and 90s. Best one was tools I was taking with me to do some work on a railroad car at Crane NWC/AAD. Had to open the the briefcase and the first thing they saw was a gov't tech manual and a letter on WH stationary. Then they asked why all the tools. I said in case I had to work on the plane in route. Told to keep the case locked and closed unless an emergency popped up. And sent on my merry way. Two 12" adjustable wrenches, screwdrivers, nuts, bolts, hoses, camera, etc.... Try that now days.
