I don't dispute that its fake, but how can those of you who are attributing its fakeness to the fact that the engines are running determine that from a still photo? Is it merely because its on a taxiway (apparently)?

Well, apart from the heat distortion behind the aeroplane, we can determine that because the guy who took the original picture from which this fake is made (Gary Watt) confirmed it on a thread on Airliners.net, and a thread on PPRUNE back in 2005 when the fake was first circulated around the internet. In the original pic the 737 was taxying for runway 34 at EGPD (Aberdeen).Al

Ok, I'll buy the heat distortion, that's a nice pick up. But, otherwise, between that and the suspicions above about the relative heigth of the grass and the taxiway, you can't really say that the engines are "on" unless you know that through external information. In other words, if the person took the picture, and was able to clean up the heat distortion, then you wouldn't be able to tell its a fake just by looking at it. You would have to assume that it would be unlikely for a plane to be sitting on the taxiway with its engines off, or something else in the picture that seemed off from normal, or you would have to be told it was fake or note that there was no recollection of such flooding ever occuring.
