@DeltaWye That makes sense. Weird things could happen right at launch.

@kenshirriff Document with a great example of a sneak circuit involving the cargo door and landing gear in an aircraft. There are some other examples out there.

If the emergency door open switch and the normal door open switch were operated, the landing gear would deploy.

(Not a sneak circuit but there was an incredible wiring error in a train and a design flaw where sounding a whistle on a locomotive caused the carriages to decouple.)

@kenshirriff @DeltaWye I'm wondering if this still makes sense with modern computers clocking away at GigHz – would pyrotechnic be "fast enough"?

@benjohn @DeltaWye In the current Minuteman guidance computer (NS-50) they apparently do the disconnect electronically with AND gates rather than explosives.
