I was already wondering how a head on collision between two large ground vehicles could end up in such fiery destruction (neither one was a fuel tanker), as I’ve seen many truck and bus accidents on U.S. highways and most don’t end up so charred.

On 10 April 2014, in northern California a large FedEx tractor trailer rig crossed into oncoming traffic and slammed head on into a tour bus.  Victims describe what sounded like a “sonic boom” as the FedEx truck instantly exploded.  It’s very odd that a front end collision would cause on explosion because the fuel tanks on both vehicles are not located in the front!  Normally, fuel tanks for buses are located further back within the chassis frame, and semi-truck fuel tanks are located on the sides behind the driver’s compartment (cab).

Pics of the aftermath show almost nothing is left of the FedEx owned truck.

Now, local news reports from that part of California say the FedEx truck was already burning when it crossed into oncoming traffic on Interstate 5.

Milliseconds before hitting the bus, the FedEx truck clipped a small car.  The two people in the car swear the truck was already on fire when it passed them.

The question now is: What was the FedEx truck hauling that turned it into a bomb?
