The 9/11 hijackers, shoe bomber and the underwear bomber prove that 90% of the security mandates for airlines are nothing more than the illusion of control. Anyone determined enough is going to find a way to do what they want to do, whether the aircraft is in the US or abroad.
I would say that a US based American Citizen employee goes through a more intense background check BECAUSE they are US Citizens. And yes any employee can wake up one morning and say they are going to blow up an airliner. But without the backing and planning of a major anti-US terrorist group, he or she will not get too far.
Now take that third world repair facility mechanic who makes $2.00 an hour maintaing and repairing US airliners. Where is his/her background check? You truly believe that these governments screen their near povery citizens to the same standards we do here?
You seem to have too much faith and confidence that the FAA demands and receives the same security standards in third world nations that they do here.
And as for your dream that airlines provide a lot more oversight than "unionistas," you are wrong.
A long time friend of mine is a manager for a domestic airline (I will not state the airline for obvious reasons) and he takes turns going to a foreign repair facility 2 to 3 weeks at a time depending on the check.
HE IS THE ONLY ONE THERE FOR A 12 HOUR SHIFT..If required they call him at the hotel.
If you think he is personally supervising each maintenance worker doing the thousands of tasks on that jet, think again. He is just making sure that each task is completed. that's it.
Non English speaking inspectors are "back checking" the work of non English speaking mechanics.
The oversight HERE is way more intense than over THERE!
Having been in this business for almost 40 years, I too know "people," Eric, including FAA inspectors.
You are not the only one with the END ALL to this debate.
