A year ago, I wrote a DVD review of this series for my other blog, The Land of Whatever, without bothering to mention that Sky King enjoyed a couple of runs on Saturday mornings in the 50's & 60's.
Sky King was a modern-day Western series, whose hero (Kirby Grant) flew into action at the helm of his personal plane, Songbird, often aided by his niece, Penny (Gloria Winters). Creativelocation uploaded this open, which includes a sponsor's spot for Nabisco (now part of the Kraft family of brands):
Like most heroes of the period, Schuyler "Sky" King fought the usual assortment of thieves and other seedier types. The series last aired as a Saturday morning entry on the Family Channel (now ABC Family) in the late 80's or early 90's. And to think that the show started off airing on Sunday afternoons!
