The posts by broadreach and Flying Lawyer are two of the best so far even though they have different opinions on the 'public forum' aspect.
If this was a discussion between warbird pilots in a Duxford crew-room, I'd see no problem with it for all the very good reasons Broadreach gave. However, if the same discussion took place in the Duxford public canteen with every Tom, Dick and Harry joining in, I'd take a very different view.
I don't think a public forum is a good place to discuss it, but my real objection is to people who don't come even close to the category John Farley described as "informed practitioners of low level displays" giving their uninformed opinions. Free speech and all that, but I think it would be more respectful of the dead if they just read and learned.
