Some airports are privately owned businesses.
But, how many hi-jackings have we had in the past 10 years?
Before 9/11, how many hi-jackings of planes did we (the U.S.) have in the previous 10 years?
The answer is: one. A Fedex Plane was hijacked in 1994 by a disgruntled employee as it took off in Memphis.
The time before that was in 1978 when a teenage girl hijacked a plane leaving out of Kansas City.
So in the 16 years between 1978 and 1994, we had no TSA and no hijackings.
Ah, weeelll, ah, up to the point where the hijacker didn't mind going down with the aircraft, that is.
