Squawk7700 - Are you saying there was only a 12kt wind from 090 or was it 12kts of xwind at the time..? (It was a fairly stiff easterly where I was further down the peninsula).
Either way, certainly not beyond the capabilities of the aircraft. Its hard to understand how things could go so wrong, although there's no doubt that executing xwing landings is a degradable skill, which you can get pretty rusty at if not practiced regularly. (Unless he did in fact get hit by a 'freak' gust of wind as reported).
So lucky they all escaped relatively unharmed. Shame to see PCO gone, it was a nice A/C, but at least no one was seriously hurt or worse.
