Can you fly a plane on Mars? JAN 30 2013
Another fine installment of XKCD's What If? series: What would happen if you tried to fly a normal Earth airplane above different Solar System bodies?
Unfortunately, [the X-Plane simulator] is not capable of simulating the hellish environment near the surface of Venus. But physics calculations give us an idea of what flight there would be like. The upshot is: Your plane would fly pretty well, except it would be on fire the whole time, and then it would stop flying, and then stop being a plane.
