The Odyssey of Flight 33 - S2-E18
Character mistake: The real speed that was reported was 3,000 knots. At one point, the plane encountered a bright flash, and violent shaking. The Captain surmised that they broke the sound barrier. 3,000 knots equates to over 3,000mph. The sound barrier (Mach 1) is about 767mph, and the captain would know that.

Other mistake: One of the crew members looks at the air speed indicator and states they are going over 2100 miles per hour. Why would a subsonic plane have an indicator that reads to 2100 mph?
Mr. Dingle, the Strong - S2-E19
Factual error: Though this episode is set in then-present-day 1961, the fistful of prop money the bartender is holding is not contemporary. It appears to be copies of 1880s U.S. Currency, though it's been reproduced as smaller, 20th Century sized bills rather than the larger ones that were standard in the 1800s. All in all, not something his bar patrons would likely be paying the bartender with in the 1960s. (00:16:40)

Thanks. It's been a long time since I saw the episode so I forgot.
