Police and fire department divers were searching Friday for the main and rear rotors of a sightseeing helicopter that broke apart in midair and crashed into the Hudson River between New York City and New Jersey, killing all six people aboard including a family of five from Spain. Those parts, along with the helicopter's transmission, the roof and tail structures have not been found since the crash Thursday afternoon, Jennifer Homendy, chair of the National Transportation Safety Board, told reporters at a briefing in Jersey City, New Jersey. Officials also identified the pilot as 36-year-old Seankese Johnson. Hemendy said the NTSB would not speculate on the cause of the crash so early in the investigation. “We are very factual and we will provide that in due course,” she said. Visibility was low in the murky river and divers were using sonar to hunt for the missing pieces. The pilot and passenger cabin of the aircraft was pulled from the river Thursday night. The victims from Spain included Siemens executive Agustin Escobar, 49, his wife, Mercè Camprubí Montal, 39, who had been a global manager at an energy technology company, and their three children, Victor, 4, Mercedes, 8, and Agustin, 10. Mercedes would have turned 9 on Friday, officials said. Escobar was in the New York area on business and his family flew over to meet him for a few days, said Steven Fulop, mayor of Jersey City, New Jersey, in a post on X. He said officials were working with the medical examiner to release the bodies for their return to Spain. Johnson regularly celebrated his career milestones as a helicopter pilot on social media. In March, he changed his Facebook profile to a screengrab of him piloting a helicopter with a view of Freedom Tower and the Manhattan skyline in the background.
