On international flights there is still no screenings of checked baggage. The only security is a baggage/passenger boarding match, made on the assumption that a passenger would not board a plane on which he checked a suitcase that contained a bomb. A plan that is a little out of date, but in keeping with the Bush administration's plan of maintaining homeland losses to keep up that old fighting spirit.
Deport, deport, deport. Now!
I would guess there are Muslims working in maintenance. There's a declared Jihad against the US, I hadn't heard it was ever called off.
