the sightings of july 19–20, 1952, made front-page headlines in newspapers around the nation. a typical example was the headline from the "cedar rapids gazette" in iowa. it read "saucers swarm over capital" in large black type. by coincidence, usaf captain edward j. ruppelt, the supervisor of the air force's project blue book investigation into ufo sightings, was in washington at the time. however, he did not learn about the sightings until monday, july 21, when he read the headlines in a washington-area newspaper. after talking with intelligence officers at the pentagon about the sightings, ruppelt spent several hours trying to obtain a staff car so he could travel around washington to investigate the sightings, but was refused as only generals and senior colonels could use staff cars. he was told that he could rent a taxicab with his own money; by this point ruppelt was so frustrated that he left washington and flew back to blue book's headquarters at wright-patterson afb in dayton, ohio. upon returning to dayton, ruppelt spoke with an air force radar specialist, captain roy james, who felt that unusual weather conditions could have caused the unknown radar targets.
