This is an acceptable WWII film that I watched courtesy of Talking Pictures TV channel, with the scenes featuring aircraft offering something for aviation enthusiasts.
The first few minutes plodded a bit with one protracted discussion between Rick and Mona and then another between Rick and newly-arrived pilot Binks; the "musical" efforts of the latter were almost irritating. But unlike another reviewer here on IMDb I thought there was good chemistry between Rick and Mona - and between Rick and Binks.
Denison's initial breeziness irked somewhat, but he performed well enough after he thought he'd sunk a British submarine. The sub-theme of class difference didn't quite work because Patricia Plunkett as Mona seemed too superior for a barmaid working in a pub popular with servicemen.
The actors playing senior naval and air-force officers were effective.
After I'd watched the film I thought that it seemed very much like a plot by Nevil Shute, and a check of IMDb showed that it was.
