"Assignment: The World" Intro (1985)

This intro was presumably used from the '70s to mid '80s (as it was seen from 1981 too).
"Assignment: The World" was a weekly program that had content determined by current events. The series was a phenomenon in PBS stations and has aired over 50 years from 1959 to 2013. It was produced by WXXI from 1966 ever since 'till 2013.
Gotta love the intro, one of the intros ever.
