It contains classified message traffic marked Secret Spoke and Top Secret Umbra. The messages record radar tracking of unidentified flying objects, often several at a time, at altitudes from about 500 to 88,500 feet. Most entries describe the objects as probably balloons. Locations, sources and many dates have been removed.
