What made me laugh was a TV report about an American defense scientist funded by DARPA who had succeeded in making half an electronic dragonfly go round a pole in circles. The aim was to produce tiny controlable flying machines, at the cost of several millon dollars.
Next Christmas I was flying a £30 chinese remote control helicopter around my living room.
Just like Kurt Schrekling et al. and their gas turbines, amateurs can still lead the way when it’s ingenuity that matters.

PS: buzz bomb was unguided , someone with wits and luck could make one from scrap, if they were stupid enough.
