Quote from the article:
“Of the 11,107 sightings since 1947, Quintanilla (Major Hector Quintanilla, Jr., Director of Project Blue Book) says, just 676 remain in the unidentified category. Only 30 of those checked out last year haven’t been explained satisfactorily.
Another 242 sightings are listed as having insufficient data for identification.”
