Bronx, New York, New YorkMarch 1962

On March 23 and 24, 1962, two witnesses in the Bronx observed what appeared to be white smoke trailing behind an object traveling across the sky at high speed.

The first witness reported seeing the phenomenon on March 23. He described an oval-shaped object with white smoke trailing behind it. The object remained visible for about five minutes. The witness noted that it moved very fast, though he did not describe where specifically he was observing from or provide other contextual details in the initial filing.

A second witness reported a similar sighting on March 24. He was watching from his schoolyard while eating lunch and observed what he believed was the same phenomenon. This witness stated that the smoke continued for a considerably longer duration, somewhere between twenty and thirty minutes. The witness watched the smoke trail but did not see the object itself. Notably, about five hours later, he observed fire engines moving toward the area where the smoke had ended, which he initially found striking enough to mention in his report.

An Air Force investigator later concluded that the sightings had most likely been caused by an aircraft with a contrail, which is a trail of water vapor condensation left behind by a high-flying plane. The investigator noted that the New York area experiences substantial air traffic, and despite the delay in gathering complete information, the duration and distance covered by the observed phenomena were consistent with the speed of conventional and jet aircraft. The Air Force found no connection between the sighting and the appearance of the fire engines five hours later, as any aircraft crash would have warranted immediate dispatch of emergency equipment and likely received wider public attention.
