How does an alloy (titanium) chain fail ?? What happens to the rider?

Has anyone on the list ever snapped an alloy or hollow-pin or drillium chain ?? I think that Regina made both drillium and hollow-pin steel chains in 1975.

What does the crash look like ?? I looked at the archive and in many cases a chain snaps on an uphill climb at low speed, is this the typical failure mode?
