I thought I'd mention a little food for thought on the first class of pilot's being trained to carry weapons in the cockpit. Out of 50 hand picked candidates, two failed the class. Of the two that failed the class, one was a former Federal Officer and the other was working as a part time law enforcement officer. All of the candidates were chosen for the first class on the strength on their previous firearm training. It was expected that none would fail the class because they were all very highly trained to begin with. Apparently the TSA has set up a very challenging course and there is currently a controversy on the "tone" of the course. Many involved in the movement to arm pilot's are unhappy with this course and the politics involved. It is preceived as unnecessarily difficult with numerous opportunities to lose your license (failed pysch exam/evals) . The TSA was no fan of the program and is charge of the program. It appears to involve a little "payback".
