In July 1947 the Army announced it had recovered a 'flying disc' near Roswell and replaced the story with a weather balloon within a day; the Air Force's later Project Mogul explanation is proposed, not demonstrated, since no specific balloon flight was ever matched.

In their own words

“not of this earth”
Maj. Jesse Marcel, Roswell Army Air Field intelligence officer, decades later · source

Roswell Army Air Field issued a press release saying it had recovered a 'flying disc' from a ranch near Corona. Within a day, Eighth Air Force headquarters replaced the story with a weather balloon. Decades later the intelligence officer who handled the debris, Major Jesse Marcel, said the material was 'not of this earth'. Witnesses described thin foil that sprang back to shape, I-beams with strange symbols, and bodies taken to a base hospital. For believers it is the moment a crash retrieval program was born.

On the record

  • The RAAF press release and the Roswell Daily Record headline 'RAAF Captures Flying Saucer on Ranch in Roswell Region'.
  • Air Force reports in 1994 and 1997 attributed the debris to Project Mogul and the body accounts to crash-test dummies.
  • Grusch, under oath in 2023, said the U.S. has been retrieving craft since at least the 1930s.Hearing, 2023
  • The Roswell information officer's 2002 affidavit was put in front of DIA in 2008 as exhibit 2 of the BAASS plan (DOW-UAP-D168, PURSUE Release 07).
  • The McQuiddy and DuBose affidavits.

In The picture

The pictureThe atomic bomb woke it up. Foo fighters, the ghost rockets and Los Angeles 1942 came first, then Roswell in 1947, the green fireballs over Los Alamos, Washington DC in 1952, the radar-tracked intercept at Lakenheath in 1956, Malmstrom in 1967, Rendlesham in 1980 and the activity around nuclear sites ever since. The …
The pictureWe caught some of it and hid it. Roswell, then MJ-12, then retrieval and reverse-engineering moved into contractors like Lockheed, Battelle and Northrop, inside waived special access programs that only a handful of members of Congress are ever told about.
