Hi Mark, I realize you're probably busy and you've got way more important things on your plate than answering some random question on the KZbins, but... When the launch abort system activated- how did it know to do that? It obviously worked very well, but I couldn't see anything from the film that gave any clue the rocket was about to explode. Do you know anything about that? What sort of sensors/information would be involved in making the decision to abort? Was this "test" that we seen here done automatically or manually? Also, thankyou for posting all these wonderful videos to KZbin. My absolute favourite is the 8minute Saturn V launch as seen from pad cameras. Your commentary on that is utterly superb and I show it to everyone I can.
