What year did the Air Force issue their first Santa Claus sighting?

On December 24, 1948, the U.S. Air Force reported that one of their radars had detected “one unidentified sleigh, powered by eight reindeer, at 14,000 feet, heading 180 degrees.” This one-time event prompted the now famous yearly NORAD Santa Tracker.
