What happened during the plane landing incident captured on video?

The video shows a very hard landing where the plane failed to properly flare up before touchdown. According to Van Cleave, the aircraft experienced a main gear collapse after a hard impact, which one pilot likened to a carrier landing. Following the gear failure, one of the engines caught fire and the plane tipped onto its side. The incident was captured in TMZ footage and another Instagram clip that CBS confirmed as verified, providing key insights for investigators examining the cause of the accident.
