On 7 January 1948, observers in the tower at Lockbourne Air Force Base in Ohio reported a large glowing object moving over the field for more than twenty minutes. Two government files sit in the archive alongside the account. This is the record of what was logged, not a verdict on what was over the base.
The telling places this about two hours after the death of the pilot Mantell. Observers in the tower at Lockbourne watched a round or oval object larger than a C-47 hold over the field for more than twenty minutes. It glowed white and shifted through to amber. Its movement is described as elevator-like, rising and dropping rather than tracking across, and at one point it appeared to touch the ground.
What is on the record
The testimony here is thin. One telling, one channel, one video, and a single resolved claimant recorded not as a person but as the Lockbourne observation tower observers. The archive holds no names, no time of day, no count of how many people were in the tower and no statement from any of them.
The paperwork is the substantial part. Two government primary documents attach to this entry: an Air Force analysis of flying objects in the United States, from the Department of War UAP release, and a Project Blue Book case file from the NARA and archive.org holdings. Both are government records rather than reporting, and they carry the entry.
One caution about the second of those. The Blue Book item is indexed under Wilmington, Ohio rather than Lockbourne. It sits in the right month and the right state, but the match between the document and this sighting should be confirmed at the file itself rather than assumed from the index line.
Why it sits where it does
Lockbourne grades L4 with an evidence grade of official record, because government paperwork rather than retelling carries it. That should not be read as a strong case in the ordinary sense. The tier measures the class of the sourcing, and the witness side of this entry is one anonymous group in one video. What the tower watched for twenty minutes that day is not resolved here.
