The same thought has often crossed my own mind. The hangar area at the city airport here is completely open to the public. I have driven my car from the street directly onto the apron many times, and I could have driven onto the runway if I’d had any reason to. Dozens of general aviation aircraft are parked there — everything from Piper Cubs to Gulfstreams — and it would be child’s play to gain access to them by day or night. Anything could be in those planes — there’s no X-ray, no sniffers, no millimeter-wave radar scanners, no physical barriers, and no security personnel on the flight line.
My question is: why hasn’t it happened already?
