This isn't really a huge surprise, since I see very little in the way of enhanced security measures on our part over here at FedEx. If the terrorists are "testing" our security, it's obvious that we are failing. When I visit our local (large) ramp, nobody is doing anything but humping freight as fast as they can, which is business as usual. I strongly suspect that it's the same over at UPS. It would be expensive to take proper precautions, and I doubt that anything will happen until the bad guys succeed and bring down an aircraft. Then, everyone suddenly gets involved and pointing fingers.
I've never seen airport police, TSA, Customs, or any other agency on the premises checking outbound packages. Nor have I seen FedEx security personnel checking on anything. That isn't very reassuring, and my opinion is that profit is much more important than safety. Lots of talk, but no action.
I, or anyone else, could easily get a dangerous item through the FedEx system very easily, and completely undetected. It's probably just as easy over at UPS.
