The Quest team heads to North Atlantic, in search of German submarine which vanished during WWII. Upon reaching the sub, the team accidentally triggers a time-travel device, transporting them all back to 1945. Even worse, the heroes must contend with some very live Nazis -- not to mention the unexpected arrival of a pack of pygmies, very much like those seen in the 1965 Jonny Quest episode "A Small Matter of Pygmies." "40 Fathoms Into Yesterday" originally aired as part of the syndicated "Funtastic World of Hanna Barbera" package on October 12, 1986. ~ Hal Erickson, All Movie Guide
