If a person fell from a plane and could land feet first on a steep downward slope could the person possibly survive?

In the movie Indiana Jones and the Temple of Doom, Indiana, a woman and a kid jumped from an airplane in an inflatable raft, inflated it while going down, landed on a steep slope, and survived.

This premise was tested on Mythbusters and found to be feasible.

Now, your question is whether you could do it with your feet depends on three things. 1) That you land feet first, 2) the speed you are falling at the time of impact, and 3) how steep the slope is.

This takes it to a whole other level. I wouldn’t try it personally. It’s not likely you’d survive, but there is, undeniably, a very slight possibility you might.
