**Most likely** Answers **1** questionPublished0

## Where it stands

**Most likely** Its tests supported it: three pieces of evidence for, one against. It needs two reviews to be accepted.

## What it predicts

- The materials described in 1947 and by Marcel match the Mogul hardware.
- Flight 4's track passes near the Foster ranch.
- No 1947 record describes anything else.

## What would rule it out

- A 1947 record describes material inconsistent with balloon hardware, or flight 4 is shown to have been recovered elsewhere.
