Diana,
I am sorry if you took my comment as a personal remark - it was not intended as such.
If you look back through MLU and other military site threads you will see people becoming quite enraged over errors in movies, books and docos.
Anyhow keep watching, as I said it is quite entertaining spotting the faults.
If you want to look at a very interesting doco there is one below. Unfortunately it has got lots of complete drivel in it for the spotters. The story of a Pan Am China Clipper caught out 7 Dec 1941 and flying back to USA from NZ the long way. All they did was follow the every day Imperial Airways flying boat route through all the established standard refueling and mooring stops. One of their "top secret" engines blew up and they miraculously found a DC3 engine (which the Japanese operated as well) to fit. Great propaganda for the time and hardly one of the leading heroic escapes of WW2 but despite the high drama very interesting and good entertainment. The public needed a morale boost in the weeks after Pearl Harbour.
