Most recent was on descent into Sonderstrom Fjord about two weeks ago. Severe (that's 'proper' severe) turbulence at FL120 that resulted in a broken toilet door. This happened just as we were crossing from the ice field to mixed terrain. No passengers on board fortunately.
Most scary was in a good old C210 on approach to Darwin when the tower vectored me clear of a cell only to put me straight into a second. Nav bag upturned, pencils and crayons all over the place. Took me ages to tidy up.
