Thanks for the link, kinda reminds me of some of the big flying boats of the past, I believe the Martin Mars is still on firefighting duty, there was a PBY on the Ramp at North Little Rock, when I was a lad, gorgeous, oil belching beast, and several years ago when I saw the Raptor at Oshkosh, two Sa-16s took off, the old Albatross of my Okinawa days, in formation, the noise of all those supersonic prop tips, was deafening, I turned around and they lifted off at what looked like a fast walk, a real contrast to the two ship P-51 departures with a whole different, man nuthin sounds like a Merlin. Delft how many airforces still have big flying boats? Yes, this is def off topic,, sorry?
