In all fairness, i don’t think you can call the Raptor a scam. Misguided, certainly, but not a scam. Peter is actually building and testing to the best of his abilities, but his strength is in computer programming, not aircraft design.
I think he still believes in the project, but some of the reality might finally be settling in for Peter which ultimately puts him at risk as he tries to save the design by shoveling more coal into the locomotive’s boiler (sorry, wrong engine for that analogy). I wish him well, but to succeed, I think he needs to switch tracks (there’s that analogy again). Sure, he took on investors, but he seems to have used that money (and his) for its intended purpose instead of lining his pockets.
I wonder if Moller started off believing in his project before it eventually became only just a 50 year investor-funded payday?
