1947 FBI Dallas Teletype on a Roswell "Flying Disc" (Part 01) in the Roswell UFO Release, FBI Vault
To the point
In 1947 the FBI Dallas Field Office sent an official teletype describing a “flying disc” near Roswell that looked like a high‑altitude weather balloon, and this item is included in a Roswell UFO collection in the FBI Vault that preserves such communications and links them to related topics for researchers and the public.
