August 15, 1952; Napa, California (BB)
5 p.m PDT. A GOC observer saw a silver colored cigar shaped object the size of a large aircraft overhead at an estimate altitude of 10,000 feet moving on a SW course at an estimated speed of 800 -1000 mph. The winds in the area were from the SW. No sound was heard from the object. The object was observed for 30 seconds.
This incident was exlained as a balloon but behaved more like a meteor, the description of which at the time of day is unlike either one. It appears to have been going relatively fast for a balloon and the description of a shiny cigar certainly doesn't sound like a meteor. It appears to have been moving against the wind.
