This has been an extraordinary thread.
The number of people whose lives Danny changed for ever is fantastic. And that there should be a thread such as this is, in my experience of PPRuNe, unprecedented in that there is not one expression of anything but admiration for who Danny was and what he did, and sorry at our loss and that of his family.
I shall also be making a donation in his memory, but perhaps the best tribute we can all pay him is to remember in our flying his enthusiasm, his professionalism, and, most of all, everything he ever taught us.
It's quite humbling, really. We probably would all wish to receive such tributes after our own demise as have been paid to Danny. In truth, not many of us will.
