Incidentally, are you aware that as an aeronautics (or related) student you have the right to use the Royal Aeronautical Society's Library at 4 Hamilton Place (just off Picadilly, I usually get off at Green Park tube). Best thing to do is phone them, ask for the librarian and tell him who you are and what you're looking into before you go. He'll then have a table set aside for you with all the known texts on the subject of the day piled up.
The society's phone no. is 0207-4993515.
