Is it true: Roswell UFO Incident?

Partially True80% confidence

Partly — it's more complicated than the claim suggests.

The government did lie about what was recovered at Roswell — it was not a weather balloon. It was a classified Project Mogul balloon for detecting Soviet nuclear tests. The 1994 GAO-requested Air Force report "The Roswell Report: Fact versus Fiction" declassified the actual origin. The alien-recovery narrative, popularized by books in the late 1970s-80s (Berlitz & Moore, Friedman) and the 1995 "alien autopsy" hoax, is not supported by primary documents, and the purported eyewitnesses surfaced decades after the event with conflicting accounts.
