While I've now flown enough miles not to get alarmed, I'm still surprised
to look out the window of the 747 in which I'm traveling and see the
engines swaying in turbulence.  How much do the engines actually travel,
how does this affect their efficiency, and what type of construction is
used that permits such wild movement without the engines tearing off and
leaving us without power?  Thanks for your answers.

Bob
