stolen technology ideas
It's great to see some of the technology ideas in this 1960's Ultraman come out many years later in American movies. Those Japanese sure were ahead of Americans.
Such as the chest communication walkie-talkie. That isn't seen again until 1990's Star Trek Next Generation. And the second Science Patrol aircraft in Episode 14 looks identical to the spacecraft Steve Austin flies and crashes in the pilot of the 1970's Six Million Dollar Man.
