Project Blue Book Case #1273. On June 13, 1952, an unidentified object was observed at Middletown, Pennsylvania — the location of Olmsted Air Force Base, a major Air Materiel Command logistics depot. This case preceded the September 1952 Olmsted unknown (Case #2093) by three months, making the base a repeat contributor to Blue Book's unresolved files.
Olmsted AFB handled supply distribution and maintenance for Air Force operations across the northeastern United States. Its personnel had extensive familiarity with aircraft of all types, making their inability to identify this object significant.
June 1952 was in the building phase of the great wave. The Middletown/Olmsted area's contribution of two unknowns during 1952 paralleled the pattern seen at other logistics depots like Kelly AFB and McClellan AFB.
The case was classified "Unknown."
