I am always amazed at how this anime made use of time dilation so well. Also loved the attention to detail when they were at high speed the colors of the star change, like a doppler effect but with the light as light coming from the front is blue and when passing becomes red shifted, brilliant! This anime was so far ahead of its time.
I remember watching the Gun Buster series back in the 90's. This scene where Takaya boards the Lexington was always my favorite part. At least she got closure.
