In a military training camp some recruits get educated in parachuting. After
some weeks of training on the ground they have to do their first jump.

Before the jump the instructor recalls, You leave the air plane, count till
three and pull the cord. The parachute should open then. If it does not, pull
the emergency cord. Then the emergency parachute will open. On the ground there
is a lorry waiting. We will meet on the lorry again. Good luck!

The first recruit jumps, counts till three and pulls the cord. Nothing happens.
He pulls the emergency cord. Nothing happens. The recruit is not surprised and
says, As far as I know the army, I bet the lorry will not be there, either.
