Part 4/8:
A commercial pilot and flight instructor, Robert Katz, shared insights regarding the crash, painting a picture of an unexpected and catastrophic event. In his 43 years of experience, Katz suggested that there appeared to be a rapid and disintegrative failure of the aircraft, likely stemming from neglected maintenance. He speculated that the plane's abrupt loss of control could also indicate a catastrophic mechanical failure.
Katz elaborated on the situation by revealing that the jet climbed rapidly at a rate expected of such a high-performance aircraft, but then vanished from radar just 1,400 feet above ground, marking the crash as especially alarming. He concluded that symptoms displayed in flight data strongly pointed towards the possibility of poor maintenance protocols.
