iStock/Thinkstock(NEW YORK) — A pilot died when a helicopter crashed onto the roof of a Midtown Manhattan building in a hard landing on Monday, filling the air with smoke and clogging the city streets with fire trucks, according to police and fire officials. The pilot, Tim McCormack, was the only person on board the privately owned helicopter, said police and fire officials.No one else was injured in the crash, which took place in the heart of New York City, just blocks from Times Square, according to city officials.It’s believed to be an accident and there’s no indication of terrorism, a senior official with the Federal Aviation Administration (FAA) told ABC News.The cause of the “shocking, stunning incident” is unclear, said New York City Mayor Bill de Blasio.“There is no ongoing threat to New York City,” the mayor added.The hard landing sparked a fire that has since been extinguished, though officials said fuel is leaking from the Agusta A109E helicopter.The crash — which took place shortly before 2 p.m. — came on a rainy New York afternoon. Both Newark and LaGuardia Airports are in a ground stop due to visibility and thunderstorms, according to the FAA.The pilot took off from the 34th Street heliport on the east side of Manhattan and was heading to Linden, New Jersey, officials said.“This could have been a much worse incident,” the mayor told reporters. “Thank God no other people were injured.”The building — the AXA Equitable Building — is located at 787 Seventh Ave., between 51st and 52nd Streets.It’s a busy area of Midtown Manhattan, just below Central Park South, filled with business towers.The building is roughly between Carnegie Hall and Radio City Music Hall, a few blocks southeast of Columbus Circle and southwest of the Trump Tower on Fifth Avenue.Shauna Farrell said she was in a meeting on the 36th floor of the building “when a window fell through and we heard a loud whizzing sound of a motor.”Then she said she felt the crash, prompting herself and others on the floor to get out of the building.“We ran down. I think we were the first floor to evacuate, actually, because we felt it so quickly,” Farrell told ABC News.“There was already FDNY on the scene. We were kind of just running away from the building as quickly as we could,” she said.Steven Gartner was on the 42nd floor of the building when he said he heard “a buzz and a bang — and then the entire building shook.”His colleagues “were anxious,” he told ABC News, but all managed to evacuate through the stairwell without panicking.Though the crash appeared to be accidental, New York Gov. Andrew Cuomo told reporters, “If you’re a New Yorker, you have a level of PTSD from 9/11 … So as soon as you hear an aircraft hit a building, I think my mind goes where every New Yorker’s mind goes.”The president is monitoring the situation, according to a White House official.“Phenomenal job by our GREAT First Responders who are currently on the scene,” President Donald Trump tweeted. “THANK YOU for all you do 24/7/365! The Trump Administration stands ready should you need anything at all.”The AXA Equitable Building was built in 1985 and has 51 stories and 1.8 million square feet, according to commercial real estate website Compstak. It contains offices for asset management firms and law firms and a software company, according to the site. A Citibank and sandwich shop Pret a Manger are also housed in the building.Copyright © 2019, ABC Radio. All rights reserved.
