Cigar-shaped UFO seen in Pennsylvania in 1955

Summary

A witness in Steelton, Pennsylvania, spotted a white cigar or egg-shaped object making no sound. The object maintained a level flight path for 10 minutes before fading from view. Although the possibility of an aircraft was considered, investigators concluded it could be a balloon. No photos were taken and no further investigation was conducted, with the report marked as "insufficient data for evaluation." The report notes there was no interception or physical evidence, and it suggests the sighting could be linked to a nearby naval operation.
