Chugalug,
Sounds as if your (Hastings) Central Heating system would keep your "dicky" busy for the greater part of his time - indeed it's a wonder they didn't introduce a new specialty of aircrew ("Environment Master" ? - single wing with "H&C" in mixed red 'n blue wreath).
Then your faithful slave would be left free for more important tasks - like organising the Captain's coffee and bikkies, for example !
Cheers, Danny.
