Science Ninja Team Gatchaman

Gatchaman, 20 Years Later (1x100)

:

A by-product of the Mantel plan is the Mantel condensation energy formula whose immense destructive power is kept a secret. In order to bury that equation forever, Ken goes together with Dr. Maxim towards the North Pole Sea in a cargo plane. Underway, a screw in the throttle comes loose and they get into trouble steering the plane. However, Ken puts in a clip as replacement and makes a forced landing. But the cargo plane is swallowed by a sudden crack appearing in the ice field.
