When the airplane finally stopped bouncing/leaving the runway, there was only 1000 Ft of runway remaining. The drag from the collapsed right main gear and the deceleration of going through a chain link fence might have prevented this from being so much worse. The airplane could have continued on across the highway, into another ditch and possibly impacted other structures. I'm sure the crew is devastated, but everyone got out alive and well and that's by far the most important thing.
