In this Dec. 17, 1960 file photo, the wreckage of a United airliner sits in the middle of 7th Avenue and Sterling place, the day after it crashed into the Park Slope section of Brooklyn following a midair collision with a TWA propeller plane one mile above New York City. It was the deadliest air disaster up to that time, killing all 128 people on both aircraft and six on the ground. (AP Photo, File)
