Weird Movement question

[JmOz]

I'm thinking of addidng a somewhat weird power to a base (or maybe a vehicle, have not decided if it's going to be stationary or not), want to check if it is legal:

I want to give it a huge leaping power, that is for the people inside of the base to use while leaving the base, essentialy a giant cannon that shoots them to where they need to go and a anti grav generator to slow the decent somewhat , would this just be Superleaping 10" Megascale +1/4, plus other modifiers or would it need UBO?

Second if this power was placed in a vehicle would it need 0 end as it is not being used for the movement of the vehicle itself?

I could certainly see defining a "rocket assisted launch platform" or like device that way (among others). It wouldn't need UBO any more than the Teleportation deviced described in SH do -- but it wouldn't affect the Base or Vehicle it's part of, either. It would either need an END source (like a power plant END Reserve) or to be bought to 0 END.
