The 3rd act was a collection of recreation WW1 planes.
All made by a group of volunteers based on original plans
They flew around casing each other. They were fairly slow as the original ones were.
The 2 red plane is of course a recreation of the Red Barron plane.

These look like paintings and some of my favorite photos of the day.
They didn’t do any aerobatics but just see the simple fabric planes fly was cool.
Also easier to take pictures off.
