The Kobe Bryant Crash: Three Main Theories Emerge
Theory One: Loss of Situational Awareness: The pilot flew into clouds, lost his way and crashed while trying to avoid terrain and figure things out. This will almost certainly be the top theory of investigators as they sort out the details. The helicopter as a VFR flight should not have been flying in such weather. On an IFR flight plan, things would have been different. The pilot would have been flying higher, he would have gotten specific clearances from ATC that would have kept the aircraft high above obstacles and the flight would have been handled until just before its planned touchdown at Kobe Bryant’s Mamba Sports Academy in Thousand Oaks, California.
Theory Two: Loss of Control: The pilot lost spatial awareness then control of the helicopter and crashed into the terrain. Based on flight records, this is almost certainly true. But it begs the question, why did he lose control, which is better explained by Theory One.
Theory Three: Stall: The pilot stalled the helicopter. Realizing he was too low, the pilot could have attempted a climb that was too fast too soon and stalled the helicopter. If this is so, it was most likely what’s known as a rotor stall, in which the rotor rpm get too low to support the weight of the helicopter, which then falls to earth with almost certain fatal results to all aboard. An RPM stall is difficult or impossible to recover from.
The conclusion will very likely be some combination of these three. It’s highly unlikely the cause will be mechanical, as all indications point to pilot aeronautical decision making (ADM) and the subsequent loss of situational awareness and control of the helicopter, regardless of how that control was ultimately lost.
