Here's another aviation joke I always hear from my Pilot friends:
An airliner cruising at 30,000 feet over the Pacific Ocean, suddenly lost all its engine. The cabin intercom sounded "Ladies and Gentlemen, this is your Captain speaking. We just lost our engines. Fasten your seat belts and assume crash landing positions. I will do my best to land this baby as smooth as possible on the ocean".
At this juncture, a terrified little old lady asked the Flight Attendant "Pardon my asking Miss Stewardess, but are there sharks in the ocean below?"
The Flight Attendant calmly replied "Yes, I am pretty sure there are sharks down there. But worry not, we have a bottle under your seat to cope with emergencies like this. Just rub the special jell on your face, arms and legs".
Seemingly appeased, the little old lady replied "That's very assuring of you my dear. So, meaning will the sharks not eat me anymore?"
The Flight Attendant knelt beside the lady and said "Oh I am sure the sharks will eat you just the same but wont enjoy that much".
