How they manage to pick out "bomb" from a blurry pixel on video taken with low resolution amateur film is beyond me. I mean, the basic logic of the video is "This photo is a picture of a bomb. The bomb is a circle shape. Therefore all circles must be bombs. These circles on the World Trade Center are bombs." Personally I think they're gigantic oranges grown from bonsai orange trees in the world's highest flower boxes. More likely the ones on the are glare from the sun, artifacts from the stuffty video compression, window cleaner scaffolds, broken windows, or any number of other totally mundane phenomena. The ones on the plane could be lights, or metal caps for instruments or other compartments people need to access, or patches in the wings, or any number of other things you would likely see on a plane.
As for the face, it's just an arbitrary pattern that humans interpret as a face. See the face on mars, virgin mary in toast, pictures in clouds, etc. It's a strange coincidence but that's just it, it's a coincidence. Look at enough pictures of smoke from enough angles and you can see anything you want to see.
