The file does not contain any documents from 1943, the paper trail starts in early 1944 with a request for information concerning 2nd Lt. Koenig. This bounces around as his unit was first thought to be 20BG, then to 8th AF, then to European Wing Air Transport Command until finally it lands with 558 AAFBU (20th Ferry Group) ATC, Nashville Municipal Airport who confirm on 29th May 1944 the crew details. They state that Koenig was the Navigator aboard 42-3030 which was to be ferried from this HQ to the United Kingdom.

Jump to 1948, AG 704, which has reference to and quotes 1943 documents:

This document also refers to the AG201 file of Sgt. Bingham which contains the letter to the President previously referred to.
The document concludes with the evidence presented being accepted as an official report of death.
