-I've seen a small-ish one disintegrate under test.
(Some 480kg of mass in a ~600mm diameter configuration, at some 8-9000rpm maximum if memory serves)
It amazes me how hard it is to contain that kind of energy if it wants to get out. They're really terrifying devices.
Particularly when left in the hands of engineers who do not fully appreciate that any sufficiently rapid release of stored energy is indistinguishable from an explosion.
