Thanks, TennisCasey. That isn't the explanation I was seeking, but it is a good start!
There is no need to apologize; I think it is amusing. Here's what I see so far:
OP: Help! The pilots are unconscious, the airplane is leaking fuel, and we're off course, flying over Siberia. How do I land an airplane on the snow?
A1: Let scorpions loose in the passenger cabin, and the passengers won't notice that you are trying to do such a ridiculous thing.
A2: I like to land airplanes on snow. It is better than on a runway; snow is fluffier!
A3: Snow is fluffier in some cases but not others. It is worse in cases where there are sharp rocks just under the snow.
A4: I never land airplanes on snow. I always make sure that we never get to that point, because my flights always have conscious pilots, don't leak fuel and stay on course.
A5: How are you defining snow?
A6: If all flights landed on snow, it wouldn't be a big deal.
