While they talk about how William Wyler went up in a B-25 and lost his hearing, they show footage of a B-24. A B-25 Mitchell bomber has two engines. A B-24 Liberator has four engines.
Steven Spielberg mentions several times a B-25 US bomber aircraft. The video shown is in fact a B-24 Liberator. One obvious difference is that a B-25 Mitchell has two engines and a B-24 Liberator has four engines.
In the final installment, the narration mentions that John Ford's casket was draped with an American Flag he received when he was at Midway during the battle. However in the news photo showing John Wayne standing next to Admiral Ford's casket, the Flag draped over it has 50 stars . In 1942 the American Flag had 48 stars. Alaska and Hawaii had not yet joined the Union.
The narration states that when William Wyler was ordered to Italy to complete a film about the Thunderbolt fighter aircraft, he thought he need more footage of the devastated Italian coast and that he went up in a B-25 (a 2-engine bomber) to shoot footage. The accompanying video is of a B-24, a 4-engine bomber.
When discussing John Ford's passing in 1973, the narrator declares that "a tattered flag from the Battle of Midway was draped over his coffin". However, the accompanying photograph of the flag on the coffin very clearly shows the off-set star pattern of an American fifty-star flag.. Any American flag flown at the Battle of Midway would have had only forty-eight stars, and a linear star pattern.
Spielberg tells the viewer that William Wyler lost his hearing flying in a B-25. He also notes that his father was a crew member on a B-25 over Burma during the war. However, the plane that they show during this segment is a B-24H heavy bomber.
