So What?
I hope that you are kidding!
As stated in the story, he drives to the taxiway w/o any questions,
Joe ramper barely has a background check before getting an airport badge and access to the ramp and aircraft,
said Joe ramper does not go thru security before access to ramp/aircraft,
Joe pilot with access to aircraft controls, ax pick, fire extigushers, knives, and many other possible weapons has to go thru TSA insecurity!
Where is the F##%$ sense in this procedure?
