Situation.
It's 70 years ago and in July 1940 and England is alone with the might of the German army, navy and air force expected across the channel any day, the only thing that stands between the Germans and the British people is the RAF. Hopelessly outnumbered they must fight for the survival of their homeland in one of the most crucial battles of WWII.
