So like the title says.
In media a prepared (i.e. not stunned or surprised) Force User is able to fall any distance and come away uninjured. This was particularly common in the TV cartoon Clone Wars. It happens in the movies with Yoda after his fight with Palpatine, or when Obi-Wan and Quigon fall from the ventilation ducts in Phantom Menace (just before they board the transport for the planet).
I'm thinking this is simply part of the Enhance power. Specifically the upgrade that lets you jump vertically. A jedi falls until they are in range of "jumping" at the ground.
Does this sound like a reasonable interpretation to folks?
