Wow — belly scrape of the runway?
Supposed to be impossible.
Guess not.
Both engine nacelles scraped the runway with the landing gear NOT lowered. The engine accessory gearbox which drives the fuel pumps, etc, is on the lower portion of the engine. These were likely damaged when the engines hit the runway - twice - and caused both engines to fail.

My uncle did that once, his Piper was not going quite that fast. As an air traffic controller in the Marine corps one phrase about 5 miles out was wheelsdown.
