Funny, no, sad really, how these things get twisted. A friend of mine was on a LHR-YVR recently and I got a text from her : "Am in a place called Calgery (sic) had to make emergency landing 'cos we were going to run out of petrol and crash!!!!!!!"
Turned out that a couple of hours out of Heathrow the captain had said they were expecting stronger headwinds than they had orginally calculated for and they might land to pick up some extra fuel. This became the 'emergency' landing ..... some people have dull lives.
