..well, i try to go from water to land, i noticed that when touching the land the plane "pops up" and destroy (Gear up or down..),i try a carrier operation else, in take off you must first unlock the plane (Choks off) then lower gear and choks on, at this point you can start the engine and take off, that is very simple, land on a carrier is more difficult for some reasons, bad forward view, and tendency to bounce at touch down, however low stall speed helps you...
