The runway for the aircraft is finished, now Shack needs an aircraft.
Shack is finally ready to build his plane. He wants to build an ultralight aircraft. The work begins. The captain has problems with the tail section and the shape of it.
In the morning the plane is ready. Shack orders to R-5 to find a spot to create an oxygen generator to produce some hydrogen. They put it under the base connected to the refinery. After that the plane is ready for a test. The captain puts on some music from W4sted's collection and brings the plane out of the hangar. But the plane has no power. Shack creates a connector on the tail of the plane and then he digs a tunnel in the hill to connect the base to the hangar and recharge the plane.
The plane is charged and the captain is ready. He turns on the engine and he takes off. The test consists on a flight around the lake. The test is a success and Shack lands on the ice.
