Esther Sherman was on an El Al flight to Israel to visit her kids and grandkids. During the flight she kept peering out the window. Since it was totally dark, all she could see was the blinking wing-tip light. Finally, Esther rang for the flight attendant.
"I'm sorry to bother you," Esther said, "but I think you should inform the pilot that his left-turn indicator is on and has been for some time."
