Cameras, HUDs, exct have all been done before like you all have said. What I am talking about is an "augmented reality" system. Allowing complete oversight over every part of your aircraft that you want, from one place. The best way I could explain it is think about flying in a videogame, with the display possibilities it gives you and the viewing capabilities.
Modern tech can make flying just like that, but hasn't because I don't think anyone has the drive or the vision to do it, or is quite simply happy with just maintaining the status quo and pulling in their multi-billon dollar profits.
The system would be for the most part universal, able to be used on everything from a Honda Accord, Cessna, or Mosquito... to a 777 or Skycrane.
The hundred of hours and thosands of dollars comment was in regards to just building a working prototype/proof-of-concept.
