The LIMs on the spike of Mr. Freeze actually shoot the train up higher on the spike. Basically the sensation is you feel yourself slowing down going up the spike and expect that brief moment of hangtime and then you feel this small burst of speed and you are going even further up the spike. I may be wrong but I could have sworn they fired in reverse too making the train go down the spike faster than gravity would take it.

The spike LIMs on Freeze basically feel like a chain lift, as on a Boomerang, but without the attendant noise, jerk and bounce. I'm pretty sure they simply shut off when the train reaches the top of the spike.
Flight of Fear is blocked so that a second train could be launched after the first train clears the mid-course brake...in fact that would be necessary for the ride to run four trains as designed. But Paramount has never operated the ride in that fashion. The other compact twister LIMcat coasters (Joker's Jinx, Poltergeist, Mad Cobra) do not have a mid-course brake, and so a second train cannot launch until the first train passes the safety brake at the end of the ride.
(look here for more about roller coaster blocking systems)
Well actually, I was just surfing the US Patent Database, and in the description of a Schwarzkopf looper, it says the ride can be propelled by other means such as a linear device or liquid filled piston. (hydraulics?) Click here to see the patent. The last few paragraphs are in "easy english" and are actually quite interesting. (To me at least)
EDIT: I forgot to mention that the patent is from 1979, proving linear technology isn't that new. Also, the quote about the linear motor is about 1/2 way down the page under "summary of the invention."

What do you mean by relatively new? My post before yours just explained that they are at least 24 years old (1979). Not saying people from 1979 are old, just explaining that I don't think 24 is new. ;)

Well, more specifically I meant that I thought (or perhaps just assumed) LIMs weren't used on a coaster until Flight of Fear. While Schwarzkopf's 1979 shuttle loop patent does state that propulsion can be provided by a linear motor, we all know that Anton only used weight-drop and flywheel launches on his shuttles (well, except for reverse-incline tire-driven lift on Prater's Wiener Looping ;) ). My question is, what was the first coaster to actually use linear induction as means to propel the train?

I think it was a mine train coaster at one of the Disney parks that was the first to utilize LIMs. The LIMs aren't used to launch the coaster, just as a means by which to keep the coaster train moving at a steady pace. If only I could remember which one it is... As far as I know, the Flight of Fear clones were the first coasters to use LIM's as a way to launch the coaster train.
