Exactly right. The angle on the video is so high and far away one can't possibly expect to see the actual explosion which is down on the street behind the buildings. Being a crappy video with no color doesn't help either.
What we're probably seeing is the immediate aftermath of the explosion-- some type of debris being launched followed by the smoke plume from the explosion below.
I’m on a tiny iPhone 7 and if I zoom in, I see the initial shockwave. I still hsven’t sorted out if the RV was the source of the blast.
I was in bed with my husband one night when we were visiting relatives ‘Up Nawth’.
There was a powerful thunderstorm going on, and at one point I am certain I felt a sort of ‘shock wave’ hit the room and enter my body before I even heard the (very close) thunder - probably the loudest thunder I’ve ever heard. I don’t recall seeing lightning at all.
I ran this experience by a scientist, who told me that I somehow had confused ‘before and after’.
But I knew what I had experienced. I had started to yell, ‘What was That???’ a split second before we heard the thunder.
I think there are probably lots of odd phenomena that our instruments can’t yet track/record properly.
