I was only on a DC-8 flight once where this was used.  The pilot said he
had just been given a new clearance for approach (into Dallas) and
wanted to take it, as we could cut some time.  But he had to make a
rapid descent.  He warned everyone that there would be a whole lot of
moving and shakin going on, and lots of noise.  He was right, but we
sure did loose altitude fast.
