On the ground at JFK airport, after a passenger stood up early to get his luggage, a JetBlue flight attendant named Steven Slater told him to sit down. The passenger refused, and opened the overhead bin as Slater approached, and his luggage fell out and hit Slater in the head.
Then Slater got mad - cursed out the guy on the PA system, deployed the emergency slide, grabbed a beer from the beverage cart, and slid away. The police caught up to him at home, where he was allegedly having sex with his boyfriend.
For your enjoyment: a firsthand account, lots of people rooting for him, and the Ballad of Steven Slater.
