NEW YORK: A helicopter crashed on the roof of a rain-shrouded midtown Manhattan skyscraper Monday, killing the pilot and briefly triggering memories of 9/11, after an erratic trip across some of the nation’s most restricted airspace. Authorities said they did not suspect terrorism.

The crash near Times Square and Trump Tower shook the 750-foot (229-meter) AXA Equitable building, sparked a fire, and forced office workers to flee on elevators and down stairs, witnesses and officials said.
