Exactly my point with the air marshall. He wouldn't be there to fly the plane. He's there as a deterrent.
Much like any security guard. Except unlike most security guard, he's armed.......
Forgive me, but I feel MUCH safer NOT having an armed guard in the coughpit. And my dislike of them is simply a numbers-game thing:
I do not hold pilots up as some sort of super-heroes, to me they are just professionals doing a job, just like in many countless other workplaces. But due to a culture that has been there since planes were invented, the level of ¨professionalism¨ is very high. For someone to get through to sitting in the coughpit of a commercial airliner requires many years of not stuffing up. I suspect that the chances of mental illness being detected in a pilot are probably higher that those of detecting same in a security guard (¨air marshall¨).
I also am suspicious (totally my opinions and feelings here - obviously), of why anyone would want to become an airborne security guard.
A pilot must have a passion for flying, or at the very least a love of the notion of being a pilot, to get through the years of work required to make it. What is the passion that drives an air marshall to become one?? A love of guns? A love of the idea of being the only person to be armed in a plane full of people?
And a security guard would have to sit in the coughpit the whole time. If he went back to the cabin every terrorist would know exactly where to get a gun.
One thing I will add to this thread is simply an observation: both in the case of the Malaysian guy heading off south into the never never, and this guy gliding down into the hills, both incidents involved people who were VERY passionate about flying, to the extent of home flight simulators, etc. To these people I suspect they wanted those last moments to be in control of the plane, not just do some crazy dive. I also know that some people are capable of mass-murder by remote, but could not bring themselves to slap a lady in the face. These people may well be disuaded from attempting their picture-perfect suicide, if they had a hostie or someone in the way. For that I support two-person rules.
Statistically though, even despite the AMAZING AND UNPRECEDENTED interest the world media has in crashes this year, I am still more fearful of my cab ride to the airport than the flight itself.
