Sepulveda Pass Transit - Maglev?

While looking up the history of planning for the San Fernando East-West Rail project (which is today's G Line BRT today), I came across an interesting diagram in a 1992 document for the SFV E-W project, one of the alternatives is rail following the 101 Freeway, but at the 405 Freeway it intersects another proposed line, an LAX to Palmdale Line, which had me go down a rabbit hole and then I came across a 1990 document about the LAX to Palmdale project, which was proposed to be Maglev! It listed travel time of just a half hour from Santa Clarita to LAX!
