After an exhausting session with Victoria's Secret Police, Jim Yanik
blurted out:

It's a judgement about trustworthyness.If one can trust a military pilot
with a security clearance(and to carry a gun while flying a military
plane),why must they be psychologically tested AGAIN for being armed in a
commercial plane?

Why? Don't have an answer.

Especially when they already undergo regular psy testing
to maintain their commercial flight status.

That is NOT the case in the US. For a fact there are (and have been)
airline pilots that have a habit of no getting along well with the
other pilot(s) in the cockpit. 12 years ago one former co-worker was
sent to the Mayo clinic after I removed myself from the trip (he was
an insecure little ****)...I was the 4th guy in less than six months
to get off a trip with him. The Mayo clinic shrink's report said, "Yep
he's an asshole." This guy kept his job for another 10 years after
repeated trips to the Mayo he was finally diagnosed with Post
Traumatic Stress Disorder...pffffttt...he's outta here finally.

Or how about the Captain that was a former police officer, this guy
picks fights at layover hotels if he thinks too much noise is coming
from adjoining rooms.

If they are stable enough to pilot a plane full of passengers,why would
they NOT be stable enough to carry a firearm? (on a commercial plane)

See my two examples above.

Conversely,if a pilot is not judged stable enough to be armed while aboard
a commercial plane,are they stable/reliable enough to perform the job of
pilot if unarmed?

Fail that extra psy-test,and there goes your livelihood.
If not,please explain why.

Again we do not go through routine psych re-screening.

The extra psy test is just a way of 1;scaring off interested pilots,2;an
added obstruction solely for the purpose of limiting the number of FFDOs.

Some guys don't like guns. Some guys don't want to deal with the
hassles of securing their weapon in various circumstances. I have not
heard from a single guy that he was afraid of ANY psych screening.
Doesn't mean there aren't cases out there.

Except there's not enough Sky Marshals to put even ONE on every daily US
flight,not considering international flights.And standard practice is TWO
Marshals per flight.Chances are better that a flight has NO Marshals
aboard.

Think about it...not every single flight is a probable target. But
I've flown with lots of FAMs, especially if there are gentlemen of
arab persuasion on the flight. And now days LEOs (Law Enforcement
Officers) on vacation with their families are packing heat. As I
posted previously...lots of guys with guns on airplanes.

BTW,I believe one is not supposed to be able to tell who the Marshals are
on a flight.

"One" being a passenger...correct, "one" being a flight
crew...incorrect.
