How come airplanes float in water?

How ignorant can people be? Half those answers are wrong. If you don't know something, don't post about it. Sorry but I'm not upmodding this story.

They get there by combination: displacement, large surface area (the wings) and boyancy...

I saw very little in the way of outright wrong answers (apart from the pressurized rubbish and the 1 or 2 "floats in air" answers :P)... being a bit unfair perhaps... :(

How is large surface area (of the wings) a distinct part of the answer from displacement (of all parts of the plane under the waterline)?

It's like some sort of idiot poem: (replace , with line break)

there wuz an air bubble, in the air plane, so that caused the plane, to float, thank god that , that air bubble wuz , there or the passengers , would have froze in the water,

but you had to laugh at the "it's on a sandbar" answer.

It floats in the air. Why wouldn't it float in water?

No further comment necessary.

yahoo answers on HN? It's funny sure, but on HN!?

To make it HN, we need a commentary on the lack of value placed on common sense engineering thinking in education.
