For years, I worked for an airline - including the years when some of the airports had the 'templets' at security.

I was working near security one day when 2 passengers from an international flight were flying domestic. One of them asked me if I could lift the templet - his carry-on bag was a tad big. I told him I would have to check it, and went to lift the bag, but it barely budged. Turns out it weighed just over 100 pounds. He said it was a piece of machinery (a gage or meter or something like that). I have no idea how he had traveled with it (it was a TPAC flight) and where he was planning on storing it on this domestic. We did not take any bags over 99 pounds. I ended up calling a ramp supervisor to deal with these guys.
