Low n’ slow

Thanks to you for the facts. Your fourth para. explains much including the usual level of thoughlessness and incompetance that, more often than not, accompanies these and like matters.

Your fifth para. touches on another and very realistic concern.

It’s worth noting that, as in 9/11 the Americans are not immune from bungling. It seems that F16’s were sent in the wrong direction so that by the time they were corrected, four commercials had impacted.

Because of the element of surprise, I do not think that it is possible to make an effective defence against an airborne terrorist – hi-jacker or not – coming at speed from a relatively short distance.
