"As soon as the cable tension failed, the dogs sprang out, engaged the shaft and Otis only dropped a few inches. Of course, modern systems use different safety devices, but the original Otis one would not work with a maglev drive."
No, but a similar system would. An electro magnet holds the dogs away from the rail, and when the power fails a spring pushes the them against the teeth.
Not that I see anything wrong with the current system...
Just about any frequency could be fatal if it's loud enough. Sound is a result of air (or water or whatever) vibrating. If that medium vibrates with enough intensity, our insides would get all scrambled from being tossed back and forth so quickly.
