I've heard that NORAD Cheyenne Mountain had (are they still there?)
diesel engines on static standby, with block heaters.  But the
flywheels were kept spinning.  A magnetic clutch could swap to
diesel power in a fraction of a second.

It's obsolete and considered as less reliable (spinning wheel is subject to wear). Typical contemporary solution is diesel engine constantly heated - so it's always ready to use (no spinning wheel is needed to start it), and UPS just to "mask" short outages during power supply switch.
