Can anyone give me a detailed history of how Himmler had the German SS destroy rival organization SA? Thanks.

I saw a program on the History Channel about a RAF pilot that smashed his plane into a German bomber that was about to destroy Buckingham Palace. Quite fortunate, as this would have destroyed British morale. I believe the RAF outperformed the Luftwaffe spectaculary. Why do you think this is? Comments?
