Depending on who you talk to at NPRC, all or most Morning Reports generated by Army Air Corps units in 1944 perished in the 1973 fire. One of my principal rules of thumb, "Ask for Anything and Everything" - you never know when somone might get off their can and actually LOOK for something. All sorts of things have turned up over the years - things that were initially thought to have been destroyed in the fire.
Ask. They won't kill you and they can't eat you - that's illegal.
