New Mexico, 1947

Roswell

Something was recovered near Roswell in July 1947. The durable dispute is what it was, what later witnesses remembered, and whether the surviving record is complete.

Core interpretation disputedRecovery of debris is documented. The Air Force attributes it to a then-classified balloon project; claims of a non-human craft or bodies remain publicly unsubstantiated.

Claim ledger

One claim at a time.

Status belongs to a specific claim, not to a person, institution, or side.

documented

Military personnel recovered debris near Roswell in July 1947.

The recovery and the Army airfield's initial public statement are part of the historical record. The identity of the debris became the dispute.

Evidence for

Contemporary military statements and later government record searches acknowledge a recovery event.

Evidence against or limiting

No contrary evidence recorded in this entry.

U.S. National Archives

official finding

The recovered material came from a balloon associated with Project Mogul.

This is the Air Force's conclusion after its 1990s records review. Recording it as an official finding does not ask readers to treat institutional authority as proof by itself.

Evidence for

The Air Force reported that records and interviews were consistent with a then-classified balloon device.

Evidence against or limiting

Some later witnesses and researchers dispute the explanation and the completeness of the record.

U.S. National Archives

unsubstantiated

A non-human craft and bodies were recovered at Roswell.

The claim is historically important, but no publicly available physical evidence or contemporaneous record establishes it.

Evidence for

Later witness accounts and researcher reconstructions allege a second recovery narrative.

Evidence against or limiting

Government searches reported no records indicating alien bodies or extraterrestrial material; no public physical evidence resolves the claim.
