US authorities identified all nine people aboard a Learjet 60 that crashed in a residential area of Palm Beach County, Florida, on Sunday. The aircraft was flying toward the Bahamas when it plunged nose-first into the ground, leaving a crater and debris scattered across the street. No one on board survived.

The victims included Austin, Texas, residents Adam Robinson, a technology company founder and chief executive, and his wife, Helen Sharp, who worked in public relations and had opened a ceramics studio. Their children, Emma and Charlie, were also on the flight, along with the family’s nanny, Anita Maria Cetina, and two friends, Rachael Reed and Charmi Fehr.

The pilots were Jeff Gregory, 55, and Brazilian citizen Nathalia Filgueiras, 20, who lived in the United States. Gregory’s former manager described him as an experienced pilot certified to fly several jet models. Filgueiras had logged more than 1,300 flight hours and received her pilot’s licence at 17, according to her mother. She worked for Upper Jets, a charter company based in Fort Lauderdale.

The National Transportation Safety Board is investigating with assistance from the Federal Aviation Administration. Investigators said on Monday that they had not recovered the cockpit voice recorder and did not know whether the aircraft had one. They had only begun documenting the crash site, a process expected to take several days, and faced the challenge of removing large pieces of wreckage from the crater.

Communications between the aircraft and Miami air traffic controllers indicate that Filgueiras reported rain, light icing and moderate turbulence shortly before the crash. She then asked whether the plane could climb to 37,000 feet. A short time later, she declared “mayday” and said the aircraft was descending rapidly, before shouting, “We’re going to crash.”

A federal investigator said parts of the jet appeared to have separated before impact, according to the Associated Press. NASA administrator Jared Isaacman said on social media that it was too early to speculate about the cause, citing possible factors including structural issues, maintenance history and weather. Upper Jets said it was investigating and cooperating with authorities while supporting the victims’ families.
