Crash Landing.
After the pilot safely performs an emergency landing in water, she tells the passengers to remain seated and to keep the doors closed, stating that in emergency situations, as long as the doors remain sealed, the aircraft is designed to stay afloat for 90 minutes, giving rescuers time to get to them.
Just then a man gets out if his seat and runs over to open the door.
A flight attendant screams at him, “Didn't you hear what the captain said, the aircraft is designed to stay afloat as long as the doors remain closed”
“Of course I heard her”, the man replied, “but it's also designed to fly, and look how good that one worked out!!!”
