Maybe it was the lack of peanut snacks that drove the guy crazy. A person can only take so much, you know.
Yes, though peanuts are still on some flights. When I flew from NH to Pittsburgh by way of Balt., I noticed we got peanuts on the way to Balt., but from Balt to Pitt., it was honey roasted peanuts all right (Southwest. Ding!)
On my way back I noted a video screen at Pitt. International Airport with helpful info for travelers from the TSA, as we stood in line to go through security. At one point it expressed the consequences one would face if they joked about having a bomb, etc.
Important info from the story is that he had pulled wires down from the ceiling in the restroom and had moved the mirror.
