I witnessed the whole episode from the balcony of my riverside suite here in Natchez, Mississippi. The man backed down the boat ramp to unload his kayak. As he prepared to drive out, his vehicle was in reverse. He gunned it, laying rubber in the process. It was too late when he realized that he was in deep trouble, in fast flowing waters. He was traveling backwards down the ramp at a high speed.
The splash covered the cab from the back through the truck bed. I could have started my video here, but decided to call 911 first, thinking they might be here in time to latch on to the truck and pull it out. Not so, as the truck began sinking shortly after he scrambled out of the driver-side window. Just before that, he did try at great motor speed revolutions to drive out of the river, while the vehicle was bouncing in the waves. Guess he thought the tires would act as a propeller.
