Science Ninja Team Gatchaman - Season 1 Episode 3 : The Giant Mummy that Calls the Storm 1980

Deadly crashes involving passenger planes keep happening. Ken, who's investigating these occurrences, encounters a boy named Makoto. The boy is awaiting the return of his father who was reported missing in one of the accidents. Makoto's father is the younger brother of the inventor of Uranless, Dr. Takahara. The string of plane crashes has been caused by Galactor. They are intent on getting the Uranless, since it is capable of neutralizing the means of propulsion of their giant mummy. Ken has encountered the mummy in his Cessna before, and because of that incident, he has data concerning the propulsion system of the mummy. He contacts Dr. Takahara in order to get the Uranless. He meets Makoto's father, who miraculously survived the crash. But it's Katse in disguise. Katse battles with Ken and escapes. Makoto blames Ken for torturing his father and Ken promises him to bring back his father whereupon he gets the pin hiding the Uranless. The giant mummy appears at the airport and Ken is able to defeat it by firing the Uranless into it. But Makoto watches Katse, still in the guise of his father, flee in an escape rocket. He accuses Ken of breaking his promise to bring his father back. Ken accepts Makoto's hate silently since he lost his father ten years before in a similar way and has had the same thoughts - namely that his father would return some day.
