I sit here looking out the window at the drizzle, and the gloom reflects pretty much how I'm feeling at the moment. Like most of you, I knew David only through our conversations here, but I can't think of one person more ready to investigate the questions, to understand the regulations, to think through the safety issues and to make sure that he was trained and practiced, ready for whatever came. It's only human nature to look at terrible events and find reasons why it couldn't happen to me - too dark, too low, too cloudy, too poorly maintained; I'd never let that happen, would I? - but something did happen, David, and only you know how you reacted, what you tried, how you fought to manage an impossible situation.
So now on this grey day, who among us can still sit here and say it couldn't happen to me.
Vale David.
