Astro Boy: Tetsuwan Atom - episode 19 - 16 Aug, 2003

Atom's new friend, Tatsuo, is a boy who loves robots. He imagines that he is a robot by disguising himself as one, and builds robots out of junk. However, Tatsuo's mother, Erika, who is an excellent test pilot, does not find this amusing, and tells Tatsuo that fantasies and dreams are of no use. Erika's last day of flight arrives, and the dangerous test pilot job will be done by robots from then on. However, the rocket explodes upon launch. The recoil destroys the facility, and all hell breaks loose. Atom saves the people who were forced to flee. However, Erika is in the rocket. Tatsuo goes to the rocket alone to save his mother. In a daze, Erika remembers her old self. (Source: Wikipedia)
