> Just like the "close door" button in elevators doesn't make the doors close any sooner than they normally would. I recently read an article (maybe even here on HN) that explained this fully. Basically, in the US, under the Americans with Disabilities Act, the doors must stay open for a minimum time (which depends on some variables). The door close button can only have an effect after that time is elapsed, but in many (if not most bases) the time after which the door automatically closes is set to that same minimum anyway.
