Audio problem: In the beginning of the show, when Sam's father tells him to get down, Sam climbs down and falls off the net. When he hits the dirt it makes a sound like he's hitting a board.

Continuity mistake: When Sam and his sister are on the trapeze and she does a double and he catches her you can see that the bar she jumped from is not moving behind her. Then when she jumps back to it, it's swinging again.

Continuity mistake: In practice, when Sam's sister tries to do the triple and he misses her, the wide angle shot shows that she is already below Sam's arms when she reaches out. But when it cuts to a close shot, she is able to almost catch his arms.

Visible crew/equipment: When driving to Denver we see the trucks with trailers go around a curve, and two modern cars are briefly visible on the right along with the knee of a crew member. The cars are probably the parked cars of the camera crew. (00:36:25)
Chosen answer: Per the Quantum leap page at http://www.scifi.com/quantum/episodes/season5.html. 8 August 1953: An enigmatic leap lands Sam in a Pennsylvania tavern, as his own grown self on the day of his birth. As Al and Gushie work frantically to locate him, Sam befriends a wise bartender (popular character actor McGill, who'd appeared in a different role in the very first "leap") and a group of coal miners. As a host of familiar-looking faces pass through the bar - with different identities than Sam remembers - Sam ponders his life of leaping with Al the bartender, who tells Sam he controls his own destiny. Pressed for more, Al the bartender simply shrugs and says, "Sometimes, 'that's the way it is' is the best explanation." Sam realizes he must right at least one more wrong before he can go home, and leaps back to tell Al Calvavicci's wife Beth (from "M.I.A.") to wait for Al, who will survive Vietnam and come home to her. The closing title cards state that Beth and Al have four daughters and will shortly celebrate their 39th wedding anniversary ... and that Sam Beckett never returned home.
