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...
You all have never been to airshow.
The Explosion is a pyrotechnic and has nothing to do with the crash.
Here’s the video:

There is a fire onboard the truck as it is spinning.
Pulling he parachutes will generally stop a spin, but if the shutes were involved in the fire, or were pulled too late, the truck is going to spin.
