**Two answers, none ahead** None is ahead yet. See what would settle it.

 

## Where it stands

Two answers have been proposed. None is ahead on the evidence yet. Two are still possible.

## Why it matters

Request or search the AC/AS-2 flying-disc correspondence and Project Sign administrative files at NARA for a copy or transmittal of the Newark letter. A copy dated before 1948 would show the Air Force had the interviews and did not use them; none would support the teletype-only reading.
