Same exact thought. I took a panoramic photo on a gondola and nabbed another one on its way past me. Literally looks like this.

The ground below, sky above, smoke around it, is continous and not sharp edged.

Could be an object that was quickly moving by during the panorama I guess though.

Why couldnt this just be photoshop? I mean we have no evidence he took pictures of anything, this could be faked in about 3 seconds in any photo editor software. I might accept video evidence, considering how many shots he got of it, it would not take long on any phone to switch from picture you video. So Im not sure why he wouldnt do that, except that its harder to fake video than pictures.

Without more evidence, this really amounts to nothing.
