"The wings became nearly vertical, and the view of the airplane was lost behind a berm," NTSB's report said. "Seconds later, the camera caught a fireball when the airplane impacted terrain."
A witness told the NTSB the plane appeared to be rocking in an "excessive" manner as it made its way down the runway during takeoff. The witness said they did not hear any unusual sounds or see the plane emitting any smoke or fire.
The plane, heading to Las Vegas, Nev., crashed in a golf course about a quarter mile away from the airport shortly after takeoff, killing two crew members and four passengers.
Police say Erik Valente, 26; James Louis Pedroza, 28; Anand Anil Patel, 28; Helena Lagos, 22; Iris Carolina Rodriguez, 23; and San Diego-based Instagram model Mariah Sunshine Coogan, 23, all died in the crash.
