I knew an American oilman en route Amsterdam/Dubai who was next to a passenger that died, they had been drinking together and the man just fell asleep but kept leaning on his shoulder, took a while to realise what had happened.He got up went to the front of the plane and asked to see the pilot----- the air hostesses thought it was a high jack and all put their hands in the air !!! hell no he said theres a man back there "dead as a mackerel", pilot said go back and I will come and pretend I know you and come and talk and see, the plane was full so they strapped the guy in his seat and left him, the oil guy was offered 2 free 1st class tickets to any destination that the airline flew to if he would return to his seat next to the dead guy-- he said yes, when he got off the plane in Dubai and the plane was going on to the Far East, the dead man was still sitting there.True story.
