I say it's "FAKE".
It could be real, but only if it was taken with an 18x mega-zoom point&shoot cameras. No way that was taken with a DSLR. Furthermore, it looks like it was shot with a veeeery long lens to give it that really "flat" look people want for portraits, which is why I said an ultra-zoom p&s. A long zoom would make the background objects look bigger and less far away.
I don't see how a fast shutter speed has anything to do with the noise in the image unless you also assume that the ISO is increased to allow for the fast shutter speed.
I'm no expert, but to get the propellers to freeze like that would take a shutter speed of something like 1/2000 seconds or something. A mega-zoom p&s with a f/5.6 (or worse) aperture would probably require an ISO of 400 or 800 to get a shot off with a shutter speed of 1/2000 seconds, even in broad daylight. Of course, your image quality would suck, but that's your fault for buying a crappy 18x mega-zoom camera.
Now, I said "real" if taken with a large zoom p&s, but honestly, why would I crank up the ISO in order take a photo of a plane moving at a far distance (assuming I'm right about using a long focal length)? The plane would appear to move slowly when standing far away, so I wouldn't need it.
Is the high ISO needed to freeze the plane? No. There's no need for it if the plane is pretty far away.
Is it to freeze the propellers? Probably not. There's no reason to do so.
So yes, while it's possible for this photo to be taken with an ultra-zoom camera, I think it's fake because the REASON for using high ISO doesn't exist.
