 Towards the end of the film, a British Spitfire flyer shoots down a  German bomber, which then falls over central London before crashing  into a railway station. This actually happened, (although the  fighter used in the real incident was a Hurricane, not a Spitfire).  The RAF pilot didnt shoot the bomber down, though; he had run out  of ammo when he spotted the bomber apparently trying to attack  Buckingham Palace. In desperation, he rammed the bomber which split  in two and crashed into Victoria Station. Incredibly, he managed to  parachute to safety. His own plane rammed into the ground at 350  mph. It was buried so deep that the authorities just left it there.  In May 2004 the former RAF pilot was on hand as the remains of his  aircraft were unearthed to make way for a new water main.
