I had a crush on Susan Dey, too.
In the early 70’s she was in a movie called “Skyjacked,” later changed to “Sky Terror.”
Susan played a hippie teenager who was, oddly enough, flying First Class on a domestic flight which was hijacked by a deranged soldier just back from Vietnam who wanted to defect to Moscow.
James Brolin played the soldier, Charlton Heston was the pilot of the plane, and Mariette Hartley played a pregnant woman who gave birth on the plane! The baby was played by James Brolin’s real-life infant son.
James Brolin wanting to defect to Moscow. I could see that.
