A little anecdote about this landing. It was a very windy day. On very short final the aircraft was caught in a wind gust, or even possibly wind shear. It dropped a wing and was blown off the extended center line. It looked so alarming that instead of photographing the event both my son and I just stared in disbelief at what we were seeing! Anyway, they managed to re-align, just about straighten up, and land hard but safely.
