New York City Mayor Bill de Blasio says that there's no indication the crash was an act of terrorism.
A helicopter crashed onto the fog-shrouded roof of a midtown Manhattan skyscraper on Monday, killing at least one person.
The crash occurred shortly before 1800 GMT on a rainy, grey day atop the 229m AXA Equitable Center at 787 Seventh Avenue, a few blocks north of Times Square.
Dozens of emergency vehicles swarmed the area, shutting down traffic and evacuating offices in one of the city's busiest areas.
The person killed is "presumed" to be the pilot, New York City Mayor Bill de Blasio said at a news conference. No injuries, either to people in the building or on the ground, have been reported.
"The helicopter is pretty obliterated at this point. It was obviously a very hard hit," de Blasio said during the briefing.
787 7th ave, #midtown NYC. We’re 1 block south. 20 mins ago there was a loud sound like a too-low #helicopter & I looked up and saw sheet of flame on roof and then smoke. News reports saying helicopter/small plane crash onto roof which would be consistent with what I heard/saw. pic.twitter.com/swY3ksLskH— Lance Koonce (@LHKoonce) June 10, 2019
No indication of terrorism
He said the cause was unknown but that there was no indication the crash was an "act of terrorism." It was not clear if limited visibility due to the weather was a contributing factor.
Nicolas Estevez was standing across the street from the building when a 30 cm piece of metal that appeared to be from the helicopter landed on the pavement just feet away.
The crash, which sent people streaming out of the building within seconds, reminded him of September 11, Estevez said.
"I saw the explosion and the smoke coming out," he said.
The Federal Aviation Administration said in a statement that the aircraft was an Agusta A109E, a twin-engine, lightweight helicopter. The pilot was the only person aboard, and FAA air traffic controllers d id not handle the flight, according to the agency.
The chopper took off from a heliport on Manhattan's east side at and crashed into the building 11 minutes later, causing a fire that was quickly extinguished by responding firefighters, officials said.
The site is about half a mile from Trump Tower, where US President Donald Trump maintains an apartment. The area has been under a temporary flight restriction since his election in November 2016.
The pilot would have required permission from air control at La Guardia Airport in New York, and investigators are trying to determine if the pilot was in contact with the tower there or at any other airport, de Blasio said.
Nathan Hutton, who works in information technology for the French bank BNP Paribas on the 29th floor, said the building shook when the helicopter slammed into the roof.
"It felt like you were just standing there, and someone takes their hand and just shoves you," he said. "You felt it through the whole building."
Trump called New York Governor Andrew Cuomo, who was at the scene soon after the crash, to offer assistance if needed, the governor's office said.
I have been briefed on the helicopter crash in New York City. Phenomenal job by our GREAT First Responders who are currently on the scene. THANK YOU for all you do 24/7/365! The Trump Administration stands ready should you need anything at all.— Donald J. Trump (@realDonaldTrump) June 10, 2019
The AXA Equitable Center was built in 1985 and includes more than 50 floors.
In addition to BNP Paribas, the building houses offices for a number of other corporate tenants, including law firms Willkie Farr & Gallagher and Sidley Austin and investment manager New Mountain Capital.
Le Bernardin, one of New York City's most celebrated restaurants, is also located in the AXA building.
The skyscraper is managed by the Los Angeles-based CommonWealth Partners. Reached by telephone, LeAnn Holsapple, the office manager for CommonWealth, said the company had "no comment at this time."
Manhattan has three heliports in operation. Rooftop helipads were banned in New York City in 1977 after a rotor blade snapped on a helicopter on the top of the former Pan Am building, killing five people.
Helicopters are a regular sight in the air around Manhattan, and they have occasionally been involved in crashes.
Nearly a month ago, a chopper crashed into the Hudson River in New York City shortly after taking off from Manhattan, injuring two people. A sightseeing helicopter went down in New York City's East River in March 2018, killing five passengers.
