Mister Rogers' Neighborhood (1968)

S28E12 Little and Big: Helicopters

While at the airport, Rogers encounters Mr. McFeely, who is preparing for deliveries via helicopter. Meanwhile, in the Neighborhood of Make-Believe, Lady Aberlin and Miss Paulifficate are tasked with enforcing King Friday's ban on yo-yos. Despite this restriction, Lady Elaine takes to the skies in her helicopter, whimsically named "Yo-Yo." She ascends into the air but fails to return to the ground, leaving the others in a state of wonder.
