Wow, I'm a bit surprised at the heat being created by this thread.
I'd like to approach it from the pilot perspective. I've been at it since long before 9/11.
Before 9/11 - I could say "Hey man, I need to stretch my legs and get some coffee." - get up, and leave the cockpit. The other guy is up there alone. I can walk around, chat with passengers, drink coffee, use the lav, take 20 minutes to get the blood flowing. It was nice.
Now, I cannot go into detail, but we are prisoners up there. My hips and legs ache like a **** and I can almost feel the blood clots forming. We have stopped drinking fluids because visits to the lavatory are so challenging. Now we are all getting kidney stones and other issues. I know, waah, waah.
But it has been the security portals that have turned the job into a nightmare. The stuff being quoted in this thread on expedited clearance for crew is brand new. Until just weeks ago, we were treated exactly the same as other passengers, except we could carry liquids. That's it. My nail clippers are confiscated just like anyone else.
TSA: "You might use this to take control of the aircraft!"
Us: "Uhh, hey dumb-***, think. We are already in control of the aircraft. With a flick of my wrist, I could kill us all."
It is maddening. People hate flying once a month because of TSA. Imagine going through that portal 30 times a month!
We have had reliable biometric systems since long before 9/11. I should have my retina scanned, or use my thumb print, and waltz right through. We've spent billions on chemical sniffers and nudie x-ray machines, yet no biometrics for crew.
End of whine. I've got dozens of TSA horror stories... some of them are very funny. As for the diplomat - I'm sorry, the terrorists have shown great imagination with shoe and underwear bombs, and impersonation is not difficult. A 20 year old TSA person is not going to recognize the world's 50,000 diplomats on sight, and if someone flies commercial, they get searched, period.
