At the airport today, waiting for my flight, I remembered a joke I heard long ago:
Passengers look out the window while their plane is picking up speed for takeoff. The runway becomes shorter and shorter and to the horror of the passengers the plane does not take off. Suddenly there is no more runway left and the passengers scream!!!
….the one BLIND pilot then says to the other BLIND pilot: “I fear the day that the passengers do not scream in time.”
