Terry,
Mess Kit wings are only to be worn by RAF Qualified Service Pilots (QSPs) on Mess Kit; they are not a casual adornment that may be worn by their partners (there are specifically manufactured brooches for that case) and they are not attached to any other form of dress, even by those who are RAF QSPs. Also, the version to be worn should have a King's/Queen's crown appropriate to the gender of the monarch at the time at which they were awarded. As a retired RAF officer, I would have expected you to have been aware of that.
Some of the background and scenery in the film is indeed wonderful, including the whales. However, in my opinion the context determines that it is NOT a 'great piece of film'
