A Spanish tech executive, his wife and three young children who were all killed in a helicopter crash while touring the New York City skyline were celebrating the mother’s 40th birthday at the time, local officials said Friday.

Siemens’ Spanish branch CEO Agustín Escobar took off in a Bell 206 helicopter at around 2:59 p.m. on Thursday with his wife, Mercè Camprubí Montal, and their three kids. The flight lasted less than 20 minutes and crashed near the Jersey City shoreline in New Jersey, killing the family and the pilot.

New York City Mayor Eric Adams identified the kids’ ages as 4, 7 and 10 in an interview with Fox 5’s “Good Day New York” on Friday. He said the 7-year-old would have turned 8 on Friday.

Jersey City Mayor Steven Fulop said in a social media post on Friday that Escobar was on a business trip and had extended his stay for a couple of days when his family flew out from Spain.

“They were celebrating the mom’s 40th bday with the tourist helicopter flight yesterday,” Fulop said.

Video of the crash showed the helicopter tumbling into the water, and one witness told The Associated Press she saw “a bunch of smoke coming out” of the aircraft.

Michael Roth, who heads New York Helicopter Tours and owns the aircraft the family boarded, told The Telegraph that the pilot had radioed in that he was landing to refuel but never arrived.

“I got a call from my manager and my downtown heliport, and she said she heard there was a crash, and then my phone blew up from everybody,” Roth told the outlet.

The pilot was identified by his wife, Kathryn Johnson, as 36-year-old Navy SEAL veteran Sean Johnson, according to Gothamist. He was a gunner’s mate responsible for fixing equipment during his time in the military and had recently moved to New York City to continue his aviation career.

Jennifer Homendy of the National Transportation Safety Board told reporters at a Friday press conference that Johnson held a commercial pilot certificate with rotor craft and instrument ratings and had accumulated about 788 hours of total flight time as of March 29.

A video posted on the pilot’s social media weeks before the crash shows him flying over the Manhattan skyline in a helicopter.

“ I’m just at loss for words. I don’t even know what happened,” his wife told Gothamist.

The cause of the crash is still under investigation. Homendy told reporters that investigators “have a lot of information, but we do not speculate.”

Fulop said on X that he is working with a family member to expedite the release of the family’s bodies back to Spain.
