The Tim Conway Show and The Tim Conway Comedy Hour were two different comedy shows starring comedian Tim Conway that both aired in 1970 on CBS. Both were rather unsuccessful as the first ran for only twelve episodes as the latter aired thirteen after both getting low ratings.
The first was a situation comedy set on a small charter airline called Triple A Airlines in which he played a bumbling plane pilot. The show costarred Jo Flynn (the two had previously worked on McHale's Navy) as his boss who was co-owner and president of the company. Only two out of the twelve episodes can be found online being #2 "Mail Contract", and #5 "All of Our Aircraft are Missing". The remaining ten are considerably lost and even the titles of episodes #1, 3, 4, 6, 10, 11, and 12 are unknown. However plots and airdates are known from TV guide listings.
The second was a variety and sketch comedy which was later revived in concept as The Tim Conway Show (1980; which is also considerably missing). Despite increased efforts by having the Nelson Riddle Orchestra and star guests such as Sally Struthers, it was canceled. All episodes are believed to be lost.
