Re: Did the Auto-destruct partially malfunction in TSFS?
We don't know that the Enterprise woudn't have been rendered completely useless to the enemy absent its fall toward Genesis. Genesis just happened to be there, and when the explosion pushed it toward the planet, it broke up in the atmosphere. That doesn't mean that the self destruct mechanism used wasn't enough to render the ship completely destroyed -- it just means that crashing into the Genesis atmosphere likely destroyed the ship before all the charges left to go off had a chance to do it themselves.
"You have been examined. Your ship must be destroyed. We make assumption you have a deity, or deities, or some such beliefs which comfort you. We therefore grant you ten Earth time periods known as minutes to make preparations."
