Rapid descent? 26,900 feet (5miles) in 15 minutes is 20 mph.

I was surprised by that too.
It is a faster decent than you’d see when on approach to an airport, it definitely isn’t as fast as I would expect when trying to reach a safe altitude under decompression.
Well, that’s 1800 feet per minute. For a vertical velocity, that’s up there.
Yeah, elevators in the Taipei 101 building go almost 38 mph.
