Once on a flight,answered a call bell to a quite irrate and very distressed man
Me "Are you ok sir?"
man "No,theres a plane about to crash into us,please tell the captain were all going to die"
As you can imagine,I was a little shocked looked out the window and yes there was a plane visible,looked big but could tell it was far away not to worry
Me"Please calm down sir I asure you its far enough away and theres nothing to worry about"
Sitting next to man was a very imbarassed looking wife,who was trying to calm him down to no effect! He wouldn't listen to me,so I asked the purser to talk to him,He wouldn't listen to her either!
By this time he had created quite a stir in the cabin,some pax laughing,others getting worried! So we asked the captain to make a pa,He explained that the 747 that flew along side us,then under us and away the other side,was at a far and safe distance.And to bear in mind that we were in an A320! so the size difference and angle made it look closer,so could the man in economy please calm down.
man shouts"hes lying,I saw the pilots faces!"
Now the general laugther in the cabin soon shut him up,About 30 mins later we landed,as man was getting off,the captain was ready to speak to him,man told captain(who had been flying 10 years) that he was a lair and it was all a conspiracy and a cover up!! He left aircraft still shouting saying he was going to the press!
Just after one very imbarassed wife got off!
