Nobody comments on the curved takeoff path in the beginning of the clip. Was this something done in the past? Does anyone recognize the airport?

It looks like an interesting way to maximize runway utilization. Stage for tows off to the side of the runway to keep the runway clear. Do a little rudder dance on the initial roll to track the path to the centerline.

It wouldn't work with students, of course.

That type of takeoff is SOP at Ephrata WA. I'm sure it is at other sites as well.
