Most private planes taking off from commercial airports (the ones where TSA generally operates) are much larger than a Piper Dakota.

(But regardless, it’s not clear that the TSA is even performing that kind of calculus.)

A G650 still loses to a motivated U-haul. :)

No argument though, just saying it's a hard problem, and the scaling issue makes it somewhat awkward to deploy security resources in proportion to the threat.

I don't have a solution. I'm not exactly thrilled with the current setup, but I try to stay quiet since I can't think of anything better.
