The Pan-Am Highway, Part Two (Superman EP0266)

In a daring bid to unravel the mystery of vanished engineering teams in the Andes, Editor Perry White, Lois Lane, and Clark Kent take to the skies in a powerful stratoplane. But an urgent call from Washington halts Kent's journey, beckoning him to a puzzling assignment away from the action. As the plane ascends, eerie flute-like sounds pierce the cabin, and a perilous oxygen shortage grips the crew. Will Superman's absence spell doom for his friends, or can he navigate the perils of duty and distance to come to their rescue?Original Air Date: November 17, 1941
