So when time comes when does someone say "ground it"?
From an enthusiastic warbird spectator's pov:
Biggest point, and really the only one that matters legally, is when it is no longer safe to fly.
Other decision-points beyond that are more a matter of moral decision-making than legal/absolute. First, I'd say that once we're down to the last 2 or 3 of anything, my opinion is that the owners need to step up and stop flying and either donate or sell to an entity that'll display statically. MAAM's Black Widow and Week's Marauder are, imho and morally-speaking, right at the threshold of what can be flown.
Second, if a specific aircraft is of specific and unique historic value in its own right. Memphis Belle (the real one), Enola Gay, Bockscar, Flak Bait, Swoose (which also falls into the first category as the last Shark Fin Fortress), etc should never fall into consideration for flying. Since they are all publicly held, they won't be. But imagine a situation (HYPOTHETICAL) where, lo and behold, some private warbird collector discovers Ski's B-25B in-tact in a barn outside of Vladivostok and buys it. He has ownership rights (USAF Lawyers nothwithstanding, I'd guess), but he'd have a moral obligation to safeguard the aircraft from risk of damage/destruction, or permanent alteration that would remove "historic fabric" from the aircraft. That means not flying it.
