Flying disc sighted over Hobson, Ohio — railroad personnel witnesses

Analysis — our summary

A report forwarded through the Eleventh Air Force (Harrisburg, PA) to USAF headquarters and Air Materiel Command describes a sighting by New York Central railroad personnel — including a car inspector, a yard clerk, a patrolman, and C.C. White — on the night of May 8, 1948 over Hobson, Ohio. The object appeared round, phosphorescent in color, estimated 6 to 8 miles altitude (approximately 31,000-42,000 ft), heading 90 degrees, and traveling at great speed with a phosphorescent trail in the sky.

As reported — verbatim from the document

Analyst notes — caveats & confidence

OCR is significantly degraded for this document (1940s scan). Witness names partially illegible. The altitude estimate (6-8 miles) is very high for a visual object; angular size of 9 inches from the ground at that altitude would require an enormous object. No photographs available. This file also contains 1948 USAF policy correspondence establishing AMC as the flying disc collection agency, references to Project SIGN, the Bakersfield California incident (two objects falling to earth, March 5 and 8, 1948), and the Horten Brothers flying wing documents. Multiple sub-documents present; the Hobson sighting is the most clearly extractable incident.
