Just quickly wikid Kings Ka, that one is actually hydraulic, so I wonder, have very high and fast launches been done using LSM? Also, has LSM ever been done vertical? Cheetah Hunt is horizontal, Kings Ka's hydraulic is horizontal. Mummy is on an incline and if Hulk moves to LSM it will be either horizontal or on the incline.
I am excited for this and really want this to happen, though it seems this will be hard engineering wise.
