Freshgasflow- have you had a look at the "Significant Event/Clinical Governance" stuff from the DofH.
I'm pretty sure a white paper was written a few years ago.
I attended a talk given by the former head of Clinical Governance for the D of H, he spoke some pretty inspirational stuff, and I believe he spent a fair bit of time in the airline industry, examining how the industry learns from its mistakes.
He recently left, and I'm a little wary of putting his name on the web, but pm me if you want.
