Spherical UFO sighted over Long Island in 1949

Summary

A civilian observer in Long Island, New York, reported in 1949 the sighting of a black spherical object with a glow similar to a propeller's reflection in sunlight. The object moved eastward at a steady speed, without smoke or noise, and disappeared into the haze. The investigation concluded it was an advertising balloon launched from Lakehurst. Despite the official explanation, the observer's detailed and clear account adds intrigue to this case.

The report includes technical descriptions and weather analysis, along with data on the balloons that coincided in timing and direction with the sighting. Although a supernatural or extraterrestrial explanation was ruled out, the observer's testimony, supported by his good vision and flying experience, leaves some mystery about the object's exact identity.
