DD,
I suspect that, as individuals, RAF personnel would be delighted to support our antipodean colleagues. I'd be there like a rat up a drainpipe! However, I'm not sure that our lords and masters really care what happened 75 years ago. Or, if they did care, they don't have the funds to support what is, IMHO, a good cause.
Shame, though. I'm sure it will be a great series of events.
