Continuity mistake: When Woody has the landing gear lowered on the burning airliner, only the right main gear comes down. When Pappy warns him that the other gear isn't down, he pulls up and goes around. As the camera pans over the plane, it shows the left gear down, and the right up. Then when Woody retracts the gear, once again the right one is down.
Continuity mistake: When Pappy is engaging a single-wing Japanese Zeke the cutaway shot shows him firing on a biplane. (00:08:35)
Continuity mistake: When Woody and Pappy fly their final attack run on the bridge, a poorly-chosen bit of stock footage turns the Japanese ground forces into German soldiers firing German "88" anti-aircraft weapons at the planes.
