Retired USAF here. That is a very abnormal pattern and I have seen tens of thousands of them in my life.
The oddest thing I have seen today is actually in relation to the helicopter crash near the canyon and the fact the USAF was on site to rescue and extract the survivors.
The USAF has only two groups capable of such a thing and those are either Pararescue or Combat Command with the closest squadron being the 58th out of Nellis. So there is no doubt the 58th would have been the mentioned group. However, the thing is that it isn't so easy for a base to send out special operations and the approval for doing so is tricky when it comes to American soil. Given that the rescue is being reported some ten minutes after the crash I just don't see that as possible from my own experience in the USAF and the fact a base commander doesn't have the authority to send out special forces on American soil even if for a rescue operation.
Point being, I think we need to find out who died on that crash.
Well it is very normal for planes to land and immediately take off during practice runs or testing as this occurs every single day from very flight wing. It's the pattern that is odd to me as the practice/test runs always follow the same pattern and never deviate. In these cases there is serious deviation which I have never seen before.
Note what I am about to write may have since changed since my Air Force days concluded but back about a decade ago and for decades before that there were two areas where all communication feeds/radio of course included were all routed through the exact same place which were:
In Northern Nevada/Salt Flats/NorthWest Utah (we simply called it "The Range")
In South Nevada/Northern Arizona through a satellite base of Nellis/A51 out of Henderson, NV.
There was nothing secretive or sneaky that I ever heard of but rest assured all communication traffic out of those locations runs through, in one way or another, those locations due to the high value testing sites.

No, absolutely not normal (at all). I have never once heard of it ever going through SFO (ever) and that includes both USAF service and also a very long history in Northern CA. I have never once heard of anything (ever) being tested at SFO and do not for one second buy it either.
