I hope he gets the severe punishment he deserves. A minimum of twenty years or so in federal prison should give him time to reflect.
Anyone working around aircraft and in secure areas has a serious responsibility and a sacred trust to our flight crews and the public. I don't view this as a suicide attempt. I view this as multiple cases of attempted murder.
I suspect his motives were far more sinister than what is commonly being discussed.
One doesn't need to stow away in an aircraft hell hole for a solitary act of self extermination. They have a beautiful bridge in Tampa he could have used.
People who can't cope have avenues to seek help and they should. When they involve innocents in their deadly plans, they have crossed a line which can not be tolerated or ignored.
The other questions is why wasn't this aircraft quarantined and Charlotte terminal locked down until his exact location was determined. Someone dropped the ball big time, IMHO.
