Spaceship and airplanes were imagined and built by scientists, not usual people...

I think I'm gonna bow out of this talk, but I wish you good tidings

I'm not entirely sure what you mean by "usual." Like it kinda has a "lesser" implication? In America airplanes were pioneered by two brothers who owned a bicycle shop. Apple was started in some guys garage, the list goes on. It's been shown great things can come from very humble beginnings.
