Man steps onto plane wing, backed by passengers

At first it sounds like a typical case of bad behavior aboard airplanes. The Mexico City International Airport acknowledged in a statement Friday that a man had opened an emergency exit and walked out on a wing of a plane that was parked and waiting for takeoff Thursday. The airport said the man had been turned over to police. But dozens of fellow passengers signed a written copy of a statement saying the airline made them wait for four hours without ventilation or water while the flight was delayed.
