This is the "mach loop" used by many European airforces for low level terrain flying.

You'll take off from EGOD, do one circuit of the loop, and land back at EGOD

The challange is to see how fast you do the loop, and how many resident complaints you can generate from your low level flying.

Just load the flight plan and follow the waypoints

I have also linked to a video that follows the flightplan.
