RE: B52 without ailerons?
Your right it had elevons. Can you name any others ? None come to my mind.
The 707 and 727 ailerons, spoilers and flaps operate similar to the 747. There were inboard and outboard flight spoilers and ground spoilers. Flight spoilers were also used as speedbrakes in that all could be raised at once. The flight spoilers and ground spoilers were used to aid in stopping.
