A friend, who drove Viscounts for Capitol Airlines at the time, had a
story about one of them.  He said that the flat (or slightly reverse)
prop pitch for braking was normally activated by the oleos compressing
as the plane's weight was applied to the main gear.  However, on one
occasion, something went wrong and the propellor braking cut in as soon
as it was armed, fortunately over the runway.  The plane then simulated
a rock, and broke its back in the HARD landing.  There was no mention of
serious injuries.
