This video has it all:
- Unbuilt aircraft concept
- Scale model (wind tunnel model) construction
- Cyanotype Blueprints
- Complete lack of an audio track
The obvious question that this video raises is… what happened with the model? Most wind tunnel models end up getting scrapped – shredded and melted down to recycle the metal. but every now and then one escapes. The company keeps it for display, or in an archive, or sometimes an employee simply takes it home. Sometimes they end up on EBay.
