Aboard a plane, an announcement by the captain was heard.
'This is Captain Sinclair speaking. On behalf of my crew I'd like to welcome you again aboard ABC Airlines flight 007 to London. We are currently flying at a height of 35,000 feet midway across the Atlantic, and I'm sorry to say that we have lost power of all our engines and will crash into the ocean shortly.'

The passengers were obviously very anxious to hear that, but were somewhat comforted by the captain's next announcement.

'Ladies and gentlemen, we at ABC have prepared for such an emergency, and we would like you to rearrange your seating so that all the non-swimmers are on the left side of the plane, and the swimmers on the right.'

After the passengers rearrange themselves accordingly, the captain made a belly landing in the ocean. 'Ladies and gentlemen, we have crashed into the ocean. All the swimmers, please open the emergency exits and quickly swim to the nearest island, which is on the right. As for all the non-swimmers on the left, 'THANK YOU FOR FLYING ABC AIRLINES!'
