Wow. I can recall a vast number of shows from that era, but this one does not ring a bell. If it was an evening show it must of been opposite of something my dad wanted to watch.
“Whirlybirds” was a made-for-syndication series, like “Highway Patrol” and “Sea Hunt,” thus different markets/localities ran it on different days and times. But, it was nonetheless a particularly popular syndicated series, and circulated rather widely.
