I’m thinking that there isn’t any EPA in Iran:
airliners.net/photo/Iran—A … 747-131(SF/1483593/M/
I am guessing that is Jet-A pouring out. 
Someone got a light? 
Move the portable fire extinguisher a few feet and it would in the middle of the stream. 
Hmmm…So that’s what that red button on the fuel panel marked “Jettison” does…
