Thanks Jon, I was wondering because I've read somewhere that Carlson Flying Tankers is looking at converting some C-130H's into water bombers (I think the Mars is to be retired) and as I've now got a 1/72 kit of the Tradewind and Mars, found they're about the same size. So as there's this big flying boat commercially available right now, I wondered why Coulson didn't go this route for a new tanker.
