*** SPOILER ALERT***
Ok...I believe Cornette has this labelled as 2/11/79, but I am going to disagree. Jimmy Snuka won the US Title in a tournament on September 1st. At the end of the match you can hear the ring announcer say that Flair is disqualified and "The Winner and Still US Champion....then it cuts off, but if he said Snuka, then it has to be 9/15.
