The navigator on the flight was probably Captain John G Moe, Jr., AAF. (Captain Moe, navigator AAF is mentioned in the link I gave).

I know he was a navigator, having received his wings in June, 1941.

There is a newspaper article, dated January 3, 1943 in the Philadelphia, Inquiry which states:

"Captain John G Moe Jr, 26, who recently was awarded a Distinguished Flying Cross for a "hazardous flight in a bombing plane from Washington to the Netherlands (East Indies) on an urgent and vital mission has been found after being reported missing on a recent flight his father, a justice of the peace, of 450 S Orange Street, Media (PA) said yesterday.

It looks like the Army informed his father on the same day (January 2) he was found.

Update: found another newspaper article which confirms this. It states that John G Moe had an harrowing experience in late 1942 when he was forced down in Greenland while searching for some missing flyers. He spent Christmas of that year in a rubber boat amid the ice flows of the northern Atlantic.
