Yes...those are people falling out...

911 wasn't the only aviation disaster to happen in New York. The 1960 New York mid-air collision, also known as the Park Slope Plane Crash, was a mid-air collision between two airliners that occurred over New York City on Friday, 16 December 1960. The collision of United Airlines Flight 826 and Trans World Airlines Flight 266 caused Flight 266 to crash into Staten Island and Flight 826 to crash into Park Slope, Brooklyn, resulting in the deaths of all 128 people on board the two airliners and six people on the ground.

At 10:21 A.M. Eastern Time, the United plane advised its company radio operator that one of its VOR receivers had stopped working (although they did not notify air traffic controllers of the problem), making it harder to navigate in instrument conditions. At 10:25 A.M. Eastern Time, air traffic control issued a revised clearance for the flight to shorten its course to the Preston holding point (near South Amboy, New Jersey) by 12 miles (19 km). The United plane was supposed to circle the holding point at an altitude of 5,000 ft (1,500 m) at no more than 240 mph (210 kn; 390 km/h)..
