i will post it in this thread as well
why it cannot bury itself
think of water, if you fall fast enough into water it behaves like concrete , crushing your body and killing you instantly
but this isnt a little human body, its a jet airliner
and this isnt water, its Dirt (way thicker)
do not believe water behaves like a solid?

"The difference is due to the fact that it takes a finite
amount of time for the water in the path of the diver to move out of the
way of the diver and the water the diver displaces as she/he enters the
water. If the water cannot "get out of the way" it begins to behave as
though it were a solid. At 10 meters this depends upon the technique of
the diver.
If the speed of the diver at the instant of entry becomes greater (as his/her altitude becomes greater) the less time the water has to
"get out of the way" as the diver hits the water. If the water cannot be displaced, it begins to behave as though it were a solid. The same
principles also apply if the fluid is a gas."
