Tonight, several comrades and I are going to "simul-tweet" an airpower film. The project effectively boils down to selecting a film, selecting a time to press "play" simultaneously, and then tweeting under the hashtag #airmovie. Tonight's film will be the Battle of Britain (available on Netflix Instant), a star-studded 1969 extravaganza reputedly containing some of the best aerial dogfight scenes committed to cinema. Expect the discussion to touch upon the relative responsibility of the Royal Air Force and Royal Navy in pre-empting Sea Lion. We will be starting at 9:30pm EDT. Anyone is welcome to join; I will be tweeting under the @GroundedUSAF handle. If it works out, we may try Firefox next weekend.
