Point well made. I recall years ago an incident occurred while working at JFK airport. One of the U.S. female officers mistakenly drove across an active runway while an airplane was coming in for a landing. The pilot had to abort the landing and increase altitude. I think it was snowing and the view was not clear plus she wore eyeglasses.

We were all given dates to attend a re-training class as to how to avoid this mishap in the future by the port authority. Whenever we came close to an airplane about to enter the runway area we had to yield right of way. But with trained eyes we would look up at the cockpit and observe if the captain gives a hand wave to let us go by. Another thing, we had to keep a good distance back from airplanes with engines running due to the gale forces they generated which would rock the vehicle as in a hurricane.

Those were the days when the FAA had a lot of clout and they would place a dummy gun in a briefcase on the x-ray belt to see if the person reading x-rays can detect it. What ever happened to the FAA, anyway? TSA seems to have made them defunct.
