Better in this instance to prove fast turnaround capability and get that gear to the ISS.

Can we call this a fast turn around?  They aren't reusing anything correct?  Fast turn around on the employees part I guess, not on the equipment.

Fast turnaround of the pad and crew for consecutive launches, one of the fastest in KSC history.

OK kiddies, now it can be reported that F9R Dev-2 is on the McGregor stage test stand being qualified for flights. Been there for several days.

No idea what the test schedule will be. She may do a few short test hops at McGregor then go to SpacePort America in New Mexico, or she may go straight there. Time will tell.

So the first hops should occur in max. 1 month? Maybe before? I think they will try to go up high in New Mexico before the barge/land landing, maybe even simulating a mission.

It may only be a single hop to test its systems, then off to SPA.

Given this one came off the line and will use production engines, it should have the redundant systems that would have saved F9R Dev-1.

(F9R Dev-1 used a qualification tank and preproduction Merlin 1D's which lacked redundant sensors)

The launch pad at SLC-4E needed a lot of fixing after the CASSIOPE launch. The structural engineers misunderestimated just how big a blast that big, white 224 foot blowtorch would cause. Wicked acoustics.

They lost a lot of plumbing, infrastructure and for certain many of the microphones anywhere near it. Lots of upgrades needed so it wouldn't happen again, especially with Falcon Heavy. Those changes had to be incorporated into the rest of their F9R & FH launch pad designs, and the new F9R / FH test stand at McGregor..
