What happened during the airplane accident described by Chris Van Cleave?

The accident involved an extremely hard landing that a pilot compared to a carrier landing. Following impact, one of the main landing gears collapsed, which then caused the engine to catch fire. The sequence of events continued with the aircraft tipping onto its side after the gear failure. This severe landing incident appears to have been unexpected and resulted in a chain reaction of mechanical failures that ultimately led to the plane's unstable final position. Despite these dangerous circumstances, the structural integrity of the aircraft played a critical role in passenger survival.
