Only slightly related: SF now texts you instead of calling back for a 911 hangup. I called 911 at the Montgomery BART station when visiting SF last week, because someone was having a medical emergency. I got dead air (despite strong signal) for about 2 minutes before I spotted an elevator call box. That helped me get the station attendant; once she was on her way, I hung up on 911 so I could attend to the person in distress. 10 minutes later, I got a text: we received a 911 hangup from your phone. if you need help, call back, tell us where you are and what happened. if that was a misdial, have a good night (capitalization from original, so probably not automated?) I think this is a good thing, for example in a situation where someone needs help but is uncomfortable voicing their emergency aloud. But it was weird to get dead air and no immediate call back. In any case, I found it an interesting experience.
