Corrected entry: Daniel refers to the landing speed of the B25 bomber as 135 miles per hour. First, no pilot, especially one of WW2 vintage, ever referred to an aircraft speed in miles per hour. He would refer to the speed in knots. (In this case, about 115 knots) Second, the B25 had a landing speed of 90 knots - a little over 100 miles per hour.
Corrected entry: It is established that Nat is 10 years old. In the scene where Claire is patching up Daniel, Nat carries in a Boy Scout book. Boy Scouts are all 12 and older. Nat should be a Cub Scout. (00:46:30)
