Here is a military version of a fuel air explosion

Pretty sure the ejected debris you claim to be the vortex of the explosion is a flaming propane tank.
I see no such thing and of course, the other cars are not obliterated, but the RV is. Because the explosives were inside of it just like both the recording and the authorities said.
Also, what is the point of the fuel air explosion video. Are you seriously trying to claim that is what happened?
