Roswell 1947: The Flying Saucer That Was a Secret Balloon
In July 1947 the US Army announced it had captured a "flying saucer" in New Mexico, then said it was a weather balloon. The fuller answer took almost 50 years.
In the summer of 1947, debris was found on a ranch in the Roswell region of New Mexico and reported to the nearby Roswell Army Air Field.
On 8 July the base announced it had recovered a "flying disc", and the Roswell Daily Record put it across its front page. The Army quickly changed its account: the debris, it said, was a weather balloon.
Decades later the story returned with claims of a crashed spaceship, alien bodies and a government cover-up.
In the 1990s, at the request of Congress, the government searched its records. The US Air Force concluded the debris came from Project Mogul, a top-secret program that flew trains of balloons to detect Soviet nuclear tests. A 1997 follow-up linked the alien-body stories to crash-test dummies dropped from high-altitude balloons to improve parachutes.
Evidence
- The front page of 8 July 1947 survives, with the Army's original "flying saucer" announcement.
- The Air Force's report on Project Mogul states that Mogul "provides the ultimate explanation for the 'Roswell Incident'".
- The US General Accounting Office searched government records at Congress's request and published its findings in 1995.
- The Air Force's 1997 report, The Roswell Report: Case Closed, tied the alien-body accounts to anthropomorphic test dummies.

Verdict
MOSTLY EXPLAINEDA well-supported explanation exists; some details remain open.
The debris is well explained by a secret balloon program, which also explains the official confusion. Some believers still reject the Air Force's account.

A balloon train from the secret Project Mogul
SUPPORTEDMatches the debris descriptions, and its secrecy explains the Army's confused statements in 1947.
A crashed alien spacecraft
UNPROVENNo physical evidence or record of a spacecraft has ever been produced.
Alien bodies were recovered
UNPROVENThe accounts surfaced decades later; the Air Force traced them to test dummies used in the 1950s.
