I met Al Haynes once (what a great man) and sat through his lecture during which he described the events leading up to Sioux. I was absolutely spellbound.
I was an usher at Douglas Bader's memorial service and ended up chatting with Enoch Powell. His opinion of Doug B remains with me as one of the most incredible pieces of character assasination I've ever heard. DBs CRM and safety awareness was not apparently that good.
