A round object sighted in Seattle in 1955

Summary

In July 1955, a witness in Seattle observed for thirty minutes an object described as round and the size of a star, apparently "bobbing" in the sky. The sighting was recorded as a ground visual observation with no photographs taken. Although the observer did not identify it clearly, investigators considered it likely to be a balloon due to the duration and movement pattern. The area was known for heavy balloon activity, supporting this conclusion.

Researchers evaluated that the description and length of the sighting were consistent with a balloon rather than an aircraft or astronomical phenomenon. Despite the lack of radar data or photos, the report concluded it was probably a balloon. Cases like this illustrate how UFO sightings are often explained by natural or common objects, especially when concrete evidence is lacking.
