I'm not sure I'm following you. You can tell there's hot air rising from a fire onthe ground, behind the trees, from the shape of the bottom of the cloud?
Well, here's what I'm trying to determine. A photograph was taken of Flight 93's mushroom cloud, and you'll see it here:

There seems to be some discussion about whether or not this image is real or a crock. As a professional...
Calculating explosion
Thanks for responding, but have to tell you that I've got no idea how to do this. I'm not a student of physics, I just came on here figuring I'd ask people who knew more about these things than I did. Is there a layman's way to calculate this?
Thanks for your time.
I'm studying a photo of a jet crash and it's subsequent cloud plume. I'm calculating that the cloud is 1000 meters wide and 7-800 meters tall, with the altitude of the cloud hitting maybe 900-1000 meters.
Is there anyway to determine if this cloud is too big to have been made by a 757...
