GREENACRES, Fla. — A Learjet 60 carrying nine people crashed onto a street in Greenacres, Florida, on Sunday, killing all aboard. The National Transportation Safety Board said the crew was flying at 35,000 feet when they reported ice accumulation and moderate turbulence. The crew requested clearance to climb to 37,000 feet to escape the icing conditions and was granted permission. Seconds later, the crew declared an emergency, reporting they were descending at 10,000 feet per minute. The aircraft struck nothing but asphalt and sidewalk on Military Trail, gouging a crater into the pavement and igniting a fire. All nine people on board were killed. The crash site is adjacent to a mobile home park where two units came within feet of the impact zone but were not directly struck. Nonstop rain and a ruptured water main hampered initial debris recovery efforts. Federal investigators are examining whether ice accumulation and potential autopilot system issues contributed to the accident, and whether key components including the de-icing system and flight recording equipment can be recovered from the wreckage. The nine victims included Austin tech entrepreneur Adam Robinson, his wife Helen, their two young children, their nanny and two family friends, along with pilot Jeff Gregory and 20-year-old co-pilot Nathalia Gadelha Filgueiras. Palm Beach County Commissioner Joel Flores said roughly 400 to 600 residents were evacuated and sheltered at the Greenacres Community Center. County Administrator Joe Abruzzo has requested an emergency declaration from Gov. Ron DeSantis to unlock funding for displaced residents and businesses. The crash site, including a half-mile debris field, remains sealed off while investigators comb the area for evidence and human remains.
