In the scene where Charles Farmer asks the employee of Dunkin Dounts for advertising on his rocket, the shot shows Farmer in front of a large glass window in front of a graveyard with a short chain link fence around it. The shot of the employee is the actual inside of the real Dunkin Donuts in Santa Fe, New Mexico. However the graveyard in the shot is a real graveyard with graves dating back to roughly 1910. The graveyard is actually behind the Dunkin Donuts. And Gina loves Richard
When the rocket launches, incredibly, the wooden barn remains unburned. In a scene during the second launch, exhaust smoke can be seen coming out the bottom of the barn walls, so it's safe to assume Farmer has designed his barn to overcome the explosive nature of the launch.
The craft's landing was much slower and softer than an actual Mercury landing. A Mercury landing on dry land would most likely have damaged the capsule and severely injured the astronaut.
