 FACT: When Jo and Bill are stuck on the tree in the Dodge Ram, the  tanker truck flies out of the tornado (at an amazing speed of at  least 30 miles per hour) and bumps them off the tree. The tanker is  then lifted back into the air, only to be dropped and explode a few  seconds later. However, unless it was some sort of extremely light  tanker, there is no way the twister could have picked up the tanker  again, but left the Dodge on the ground.
