Before Airwolf, before Blue Thunder, and before Chopper One, there was a three seasoned show that began in 1957 and ended in 1960 where helicopters were the stars.
Enter Whirlybirds, this show involved two pilots who flew around in Bell 47-G helicopters, they were either involved in search and rescue or were flying some bigwig around.
I am probably guessing that the writers of Whirlybirds had no idea that their show would end up in different formats in later years.moreless
