Abstract:
At noon on November 1, local time, a Bombardier Learjet 60 medium-sized business jet with registration number N722BD crashed in Palm Beach County, Florida, USA. All nine people on board were killed. Currently,
the list of victims has been announced, including Adam Robinson, a technology entrepreneur from Austin, Texas, and his family of four
.
45-year-old Adam Robinson was the founder of two technology companies, mainly engaged in website visitor identification and user operation related businesses; his wife Helen Sharp was a ceramics practitioner. Also killed were their 4-year-old daughter Emma and 2-year-old son Charlie, as well as a nanny and two of Adam's friends.
The two crew members were the 55-year-old captain Jeff Gregory, and the 20-year-old co-pilot Natalia Gardera Figueiras.
Co-pilot
The flight in question took off from Austin and was planning to fly to the Bahamas. While cruising at high altitude, the crew reported that it encountered icing and moderate turbulence. The aircraft then entered a high-speed dive, hit a residential area and burst into flames in just a few minutes.
In the radio recording, after the pilot left his desperate cry of "we are about to hit the ground" and "no time", communication was completely interrupted.
Flight data showed that in just one minute, the aircraft dived and fell sharply from an altitude of about 9,450 meters. The maximum vertical descent rate exceeded 32,000 feet per minute (about 9,754 meters per minute), and it hit the ground almost vertically.
Preliminary investigation by the U.S. NTSB suggests that the aircraft may have disintegrated in the air before impact. The exact cause of the crash has not yet been determined. The investigation team is focusing on verifying high-altitude icing, aircraft structure, crew operations, etc.
