Factual error: After Jason tells Olivia that he's giving up playing his music because he doesn't think he has a choice, when it cuts to the exterior shot of the rooming house, the vehicle parked in front is modern. The same type of thing happens later, when John rescues Pip from the airfield there are modern vehicles, etc, on the street in the background. (00:34:30 - 01:29:30)
Factual error: Jim Bob is shown communicating with friends in the UK via amateur radio. During WW2 amateur radio operators in most countries were prohibited from transmitting any signals until after the end of the war.
Factual error: While Jason is practicing piano at the Dew Drop he hears the horn playing outside, then when he walks out of the back door he sees Josh on the trumpet, and in the first shot of Josh we see a blue modern vehicle moving behind the bush, at the top left corner of the screen. (00:05:00)
The Return - S6-E20
Factual error: The year is 1940, and in the opening shot (as the name Richard Thomas appears on the screen) we have a view of Lower Manhattan as seen from the East River below the Brooklyn Bridge, but the problem is some of the buildings we see did not exist in 1940, such as One Chase Manhattan Plaza, which did not begin construction until 1957.

The Return - S6-E20
Factual error: Right before the scene with John-Boy and Daisy at the restaurant, there's a shot of Times Square, and two of the marquees advertise the 1946 movie "The Jolson Story," and the 1946 movie "The Best Years of Our Lives," and also reads "Picture of the Year" which it won at the 1947 Academy Awards, but this episode takes place in 1940.
