Haha then it really would look like an albatross trying to take off..

.and I don't mean the Grumman kind either
Lets see...take the 2 321's...saw the wings off outside the main gears...seal the fuselage..take the engines and hang 'em on the 340 wings.(6 engines for amphib long haul)..and have Gamco sort out some struts and side braces and mount the 340 on top of the whole mess...presto!! There you have it..a-340 amphibian
