The helicopter that struck a New York City skyscraper took off from a Manhattan helipad and was in the air for about 11 minutes before it crashed, authorities say.
Police Commissioner James O'Neill said that the privately owned aircraft took off from a pad on the East River.
He says it may have been headed to its home airport in Linden, New Jersey.
The helicopter struck the 228m-tall AXA Equitable building just before 1.45 pm local time.
