A passenger who died in an airplane restroom wasn't discovered until 2 hours after the plane had landed, a federal lawsuit says. From the AP:

The passenger, Taisuke Matsuo, 66, apparently had a heart attack on an American Airlines flight from Tokyo to Chicago during the first leg of a trip home to Indianapolis, according to the lawsuit filed Monday by his wife, Carolyn D. Watts.

After the plane landed at Chicago O'Hare International Airport on April 13, 2005, passengers and flight crew disembarked and the jet was taken to another gate for cleaning. Workers then discovered the bathroom was locked from the inside and found Matsuo's body - about two hours after the jet landed
