Captain Delker kept hand-written notes on the missions he flew into Japan from December 1944 to June 1945 in WWII. The pages are contained in a small red-leatherette, snap-closure notebook printed with B-29 Gunner’s Information File on the cover.

Captain Warren H. Delker was a B-29 aircraft commander assigned to the 497th Bomb Group in Saipan during WWII. He flew in the Tokyo fire raids of 9-13 March 1945. Later in the U.S. Air Force he flew missions during the Berlin Airlift.

Question about this artifact? Email the Collections Manager, Hal Sellars.

Every artifact in the Air Mobility Command Museum, including this one, is part of the United States Air Force Heritage Program. We are not able to loan artifacts in the museum's collection.


  • Hello! I am wondering if you could add pictures of the pages in this book to the website. I am interested in looking through this notebook for some firsthand information about WWII bombing missions for an Air Force writing contest. If this is not possible, am I able to schedule a time to come into the museum and search through some artifacts? Thank you so much for your help! – Emily
