The video link on this page is a demonstration of the Learjet 55 amphibian. Amazing stuff!
(It’s not a very clear video - the plane didn’t sink right away, so the pilots applied full throttle (it seems) and “drove” back towards the runway before evacuating! There were no injuries and the cause of the runway overrun and the salvagability of the aircraft remains to be seen. The Lear pilot must have been aware of thisaccident. OY indeed!)
