I grew up expecting to hear the "space-agey" sound used in the B&W 1960's anime whenever Astro flew.
I actually laughed out loud when I heard the strange, almost sputtering/toy lawnmower sound from the 1980's anime. To me, it doesn't sound remotely like small jet engines.
The movie seemed provide the most realistic sound for his jets -- also the fact he would most likely fire them in spurts (more fuel efficient and better control).
Was any reason given for the change in sound effect from the 60's to 80's version? At least the former had some semblance to a rocket sound.
Just curious!
