>One more thing, more practical; the G-canon doesn't ever show "Force Pull" IIRC. People are pushed directly away, choked with their feet on the ground, etc, but never lifted off their feet (possibly excepting Padme; I can't remember if she's lifted off the ground) or pulled toward the Force user. **In G-canon, levitation by the Force only happens on inanimate objects or the Force user themselves to augment leaps**. Even in Extended Universe, levitation of a living thing is almost always through the Dark power, Force Choke. – [KeithS][1]

The accepted post, answers the question of *if* Lord Vader could have saved him, why didn't he? Your question is moot, before asking if he *could*. Which he could not. N/A.
