Fantastic imagery. Did the mobile service structure shuttling between two Saturn pads/umbilical towers improve combined pad throughput much? Wondering if something like that should be considered for modern pads if launch rates do eventually go up a lot.
I've always thought that one of the best examples of a launch complex that is designed and well thought-out for a high flight rate was the Titan III ITL. Two complete pads, four-bay VIB- everything maxed out to get pretty much any flight rate the Air Force needed.
The second pad was never used. Actually sharing the MST would have limited flight rates.
Pondering a while how come in Jim's third post there appears to be images of vehicle on both pads (3.jpg vs 5.jpg/7.jpg). It looked like same pad is closer in every image but apparently 3.jpg is shot towards inland and is horizontally flipped? So the other Saturn pad was just a spare in case of CATO?
Obviously nothing like that was really attempted, with the closest being Gemini-Agena.
