A massive buildup of sightings over the United States in 1952, especially in July, alarmed the Truman administration. On 19 and 20 July, radar scopes at Washington National Airport and Andrews Air Force Base tracked mysterious blips. On 27 July, the blips reappeared. The Air Force scrambled interceptor aircraft to investigate, but they found nothing. The incidents, however, caused headlines across the country. The White House wanted to know what was happening, and the Air Force quickly offered the explanation that the radar blips might be the result of "temperature inversions." Later, a Civil Aeronautics Administration investigation confirmed that such radar blips were quite common and were caused by temperature inversions.

Now I know that it's old news and it's in almost every UFO documentary but it has never been explained!
