That’s what it looks like but there are still pics at the Daily Mail showing both aircraft flying past the explosion.
The video is too brief and not the right angle to get the full picture IMO. It also doesn’t show the beginning of the explosion.
Too bad the author of the article is nearly illiterate or those questions might already be answered.
If that wasn’t an aircraft exploding in front of the truck, the only explanation I can think of is the jet engine broke free of it’s mount, and blasted right through the cab, then exploded about 200’ in front of the truck...
