Angel" Decoy flares from a C-130
"I initially thought this was a hoax. The picture included in the first version of this message looked like it had been badly drawn. In the latest version, stills are taken from a video and are very realistic. The pictures are real and these are decoy flares. They make various patterns according to the weather, etc."

No worries, it's still a great photo! :) (It's still just smoke lol )
