A few years ago I got mission reports for all of the sorties my grandfather flew on B-24s and B-29s in WWII. All of this information is located in the National Archives in Washington DC and is public record - you are welcome to peruse the stacks and copy whatever you like at no cost. The information I was able to glean was fascinating, original after action debriefing reports on a plane by plane basis listing all crew, takeoff/landing times, enemy sightings, etc. Incredible. There is a multitude of official documents on file at the National Archives - you could research something to death if necessary.
I do not live near Washington and even if I did I think it probably would be a daunting task to locate exactly what you are looking for. I used a 3rd party research company to do the work for me - they were excellent and had all of the photocopies to me inside of a week from my initial request. The price was reasonable, less than $50.

Good luck, let us know what you find out!
