Flying under the big arch is a challenge that tests your piloting skills. Flying under the small arch not only tests those skills to the max, it also tests your ability to create a super small plane with lots of maneuverability, thrust, and stability.
If any of y'all fly through both arches, try to record it and post it in a comment below!
