Now that I have read the thread properly, you can obtain information on pilots in the RFC at the Public Records Office in England. Someone with more knowledge than myself will correct me if I am wrong, you can find the squadron diaries in AIR 27 and the records of officers are in AIR 76. These are only guides and as one forumite who has been of assitance to me in my understanding of the PRO wrote, that you must go to the PRO to see the files yourself.
The PRO's website address is;

Good luck and good hunting.
