Go to YouTube and look up ‘Star Wars Canyon’. The pilots know there are people there taking pictures, and some can’t help but show off. I bet that’s the case with this guy.
Not sure it was “showing off”...there is another video of what appears to include almost every aircraft we own that does a transit up the canyon...including a C-130, F-35, and even a Beechcraft King Air.
Looks like a training exercise at a location where tourists can get very close.
I recall stopping many times on US Highway 50, just east of Fallon, Nevada and watching navy aircraft doing practice bombing runs...they often are real close to the highway, which sometimes is lined with spectators.
