This contrail is on google earth over syria near a town/city called Al Quaryatun:

i154.photobucket.com...

It stretches right across the section which I guess represents one picture taken by the satallite.

this is the end nearer the aircraft (due to the 'neatness' of the trail.):

i154.photobucket.com...

and this is the end furthest from the aircraft, it has begun to dissapate:

i154.photobucket.com...

the length of the contrail, or at least this part of it is 12.3 miles.

Does anyone know what could have made this? Because the trail hasn't dissapated much at the far end means that it probably hasn't had time to, therefore implying that the aircraft was travelling very fast.

another thing is the that there are three seperate parts to the trail meaning it was a three engined craft I think.

also, the shadow looks strange to me, can't work out what exactly is going on.

Does anyone know on average how fast commercial passenger jets
travel? At, say 300 mph, it wouldn't be at all unusual to have a 12,
20, or 30 mile long contrail if the air at that level was moist, would it?
I've seen them stretch halfway across the sky and last for more than
15 minutes over Lake Michigan to the East of Chicago.

12.3 miles doesn't indicate a high speed.

A 737's economical cruising speed is around 500 mph. At that speed, 12.3 miles is covered in about 90 seconds. Which seems a perfect match for the state of the contrail.

That makes sense. What do you think of the shadow???? doesn't make sense to me. does it indicate that the aircraft climbed rapidly or is the topography of the mountains responsible?
