During a parachute jumping exercise each jumper in the plane was given a number,
and each man's number was called when it was his turn to drop through the fuselage
door.
When the jump master reached nine the ninth parachutist dropped through the
hole, but at ten nothing happened. The jump master again called 'ten' but again
nothing happened. Then suddenly he realized that the plane was empty except
for himself and the pilot.
"By heck! Ten is me!" he yelled, and jumped through the door.
