Flying boats don't land on the water. They “alight”.
I had that drummed into me only a few weeks ago by a long-retired flying-boat pilot (who flew Short Solents for TEAL, then DC-6, Electra, DC-8 and DC-10 airliners for TEAL/Air New Zealand). He turned 90 a couple of months ago and is one of only two former TEAL flying-boat pilots still alive. His son is a friend of mine.
