MacDill is heavily guarded at the gate - but now think about in the sky!!
Any solo Taliban wannabe can use anything to cause major destruction...trucks, planes or whatever!
Heaven knows how we can identify who they are - ahead of time - so that this does not happen!
It's a really scary proposition that faces us now.
Picture what a target a major airport is, with 747s loaded with fuel and people wing tip to wing tip at the gates.
Even worse would be a private Learjet or Gulfstream taking off from that airport and making a quick swing around to crash into that row of loaded jets.
