Contingency pad could be used as a min pad until main is back in the operation...I think the "contingency" which they're concerned about is not a hard landing, but future approval of a future request for permission to land more than one stage at a time there, using the term in the meaning of "dependence on ... the fulfillment of a condition." It's certainly better to get the environmental red tape out of the way now rather than later.I don't. These are very closely spaced. You would not want to send rockets down simultaneously at this distance from each other. I think an unexpected low-altitude wind change or misguided estimate which pushes the rocket off-course by ~100m+ in the last few thousand meters of descent is what they're protecting against. RTLS is very useful for Falcon Heavy boosters, and mildly useful for Falcon 9R, while Falcon Heavy centercore will always need a barge/ship/island LZ. I think Falcon Heavy will routinely land boosters RTLS-style on two separate pads, once it gets clearance - and each pad will have these four contingency pads positioned nearby.Missed this: "There are no plans to utilize the contingency pads in order to enable landing multiple stages at LC-13 during a single landing event."

Myself, I'd expect Dragons to return to either EAFB or VAFB/SLC-4 (if they want to prevent too much land flyover since DV2 can't actually "fly" like the Shuttle or DC) or the SLF at KSC if they are ok with it flying over populated land. Don't know if that will be an issue or not.
SpaceX, thank you for reading our collective minds and releasing this video to blow our minds

I think it will be Dragon V2 abort landing site and EOM landing site too.

Not enough propellant to do abort and propulsive landing, we have been told.But reserving just 10m/s worth of propellant during abort may allow soft parachute landing on the hard surface (a la Soyuz), so that option may still be open.

It's a video, done by an marketing animator on an unknown date about an unknown date, found on the internet.Clearly it's 100% prescient.
