A fire on a tall construction crane in Manhattan has caused its arm to hit a building as it crashed to the street below. Photos and videos posted on social media show flames bursting from the car of a crane hundreds of feet above 10th Avenue at 41st Street on Wednesday. The crane’s arm scraped the top floors of a skyscraper across the street as it fell. People ran for their lives on the sidewalk below. New York City's mayor says four people were injured. A fire officials says the crane's operator tried to put out the fire as it spread but had to flee to safety.
