If the tiny seats, delays and bad food weren’t bad enough, there’s a chance that you might encounter someone like these guys the next time you set foot on an airplane.

Gray Area

During a KLM flight from Edinburgh to Amsterdam last September, a Scottish man named James Gray attempted to open one of plane’s doors. Despite its numerous warning signs, he began fiddling with the latches before he was stopped by the cabin crew. Gray was told to return to his seat and was informed that he would be arrested when the plane landed at Schiphol Airport. He later said that he briefly mistook the door for the entrance to the bathroom and that the crew overreacted. Gray was fined $660, had to spend the night in a detention center, and has been banned from flying on KLM for five years.

The Peeing Passenger

There’s no telling what was going through the mind of Jeff D. Rubin during a flight from Anchorage to Portland last September. The 27 year-old passenger slept through most of the three hour flight but awoke with a full bladder. Thirty minutes before the plane was scheduled to land, he stood up and began urinating through the crack between the seats in front of him. Then he lost his balance, fell backwards into his seat and continued peeing. After soaking his fellow passengers and their belongings, he was eventually arrested at PDX and charged with two criminal mischief and offensive littering.

The Fresh Air Flyer

Last December, a first time flyer on a flight from Hangzhou to Chengdu in China decided that the cabin was way too stuffy. Just before takeoff, he opened the emergency exit to, as he put it, “get some fresh air.” The cabin crew managed to get the door shut, and the plane managed to arrive in Chengdu on time. While later being questioned by authorities, the naive man admitted that he had no idea that his decision was a serious security breach that put the lives of both himself and his fellow passengers in extreme danger.
