«This is the pilot speaking» — came the announcement.
«We have developed trouble in one of our engines. Please don’t worry. We are quite safe but it will mean we shall arrive 5 minutes later than scheduled.»
Nassreddin tried to calm down some of the passengers. «After all what difference does 5 minutes make?» he said.
Shortly afterwards the pilot’s voice came again.
«One of the other engines has also develole. We can fly on two engines but it will mean we will arrive 3 min. later.»
Nassreddin tried to calm nervous passengers. «Half an hour is nothing. he said, after all it’s better than walking».
A little later the pilot again spoke «I am very sorry to tell you that our third engine has failed. However there is no problem. But this will mean our arrival will be delayed by over an hour».
Nassreddin again spoke to the passengers » I only hope the last engine doesn’t develop trouble. If it develops trouble we could be up here forever!»
