Valves occasionally go to air for no good reason. B8A types such as the UF41 can be damaged all too easily when extracting them from the spring grip found in some valveholders.
Recently I recovered the valves from a couple of Tektronix scopes that were only fit for scrap. (I know that's a horrible thing to do but these were truly beyond redemption) A number of valves, ordinary B9A and B7G types, had gone to air, possibly in part due to cold and damp storage.
