Dear Mr. Armstrong,
Thank you for posting your request on History Hub!
We searched the National Archives and located a series titled Missing Air Crew Reports (MACRs), 1942 - 1947 in the Records of the Office of the Quartermaster General (Record Group 92) that includes digital images of MACRs arranged by report number.
We hope this is helpful. Best of luck with your research!
Many thanks. That may help
