Excellent 1st Season story with very good plot and writing, especially for a 25 minute story that requires fast efficient wrap-up. Look for legendary villain Robert J, Wilke, who played tons of western bad guys on almost every TV western of the 1950's, 60's and 70's. Wilkie had just finished one of his most memorable roles in HIGH NOON, filmed only a year or so ahead of this "Sky King" episode. I really like all the "Clipper" episodes of 1st Season with Ron Hagerthy as Penny's(Gloria Winters) brother. But in even the earliest shows, it is clear that a strong bond and chemistry was developing between "Sky"(Kirby Grant) and "Penny"(Gloria Winters). Likely aware of that strong bond between Kirby and Gloria, Ron Hagerthy chose not to return for Season 2 of "Sky King". Ron went on to a very successful acting career in the 50's, 60's & 70's, post-Sky King, on many of the famous TV westerns during that golden age for TV westerns. Ron made the right decision, NOT to return to Sky King, BUT I still really like him as "Clipper" in Season 1, and consider Season 1 a bit special because of the character.
