There are only 4 Mosquitos attacking the V-1 launchers in the opening sequence, but 6 loads of bombs are shown being dropped.

After crashing, the pilot jumps from his burning plane with the back of his jacket on fire. The flames are extinguished but after a short dialog, the pilot is seen walking from the scene from behind with not even a scorch mark on his jacket.

When the launch ramps are shown they are in the middle of green fields surrounded by hedges and deciduous trees. When the German guns start firing they are in pine forests and when the ramps explode you can see a quarry cliff behind them.

In many scenes where bombs are dropped, the bombs are released when the plane is almost or already right over the target. Even at low altitude, the planes doing 300-400mph, the bombs would fall well beyond the targets with such a late release.

After being hit by gunfire during a photographic mission over France, a fire starts in the cockpit of the hero's Mosquito aircraft. The fire is still visible (the flames are exactly the same height and in exactly the same place) when he reaches his airfield back in England. The Mosquito was made of plywood and any fire represented a serious danger because the structure (bonded with glues and resins) burned with inconvenient eagerness. A Mosquito pilot who allowed a cockpit fire to remain alight would have been swiftly cremated - add the oxygen delivery system to the scenario and the decorative tongue of flame in the above sequences becomes an even sillier screen-filler.

In the scene at the end of the movie when the German tank attacks the escaping British prisoners, it has a large swastika in between the drivers port and the hull machine gun. German panzers did not have large swastikas on the front.

The Mosquito aircraft carrying Highball bombs in the film use an extendable air-scoop fitted to the rear of the bomb bay. Real Highball aircraft used a pair of scoops fitted either side of the fuselage, under the wing roots.

At the cocktail party several of the officers are wearing the 1939-1945 Campaign medal ribbon on their tunics, these medals were not issued until the end of the war. This is not correct and not a goof as the ribbon was issued in July 1943 for the 1939-1943 Star. Although the name of the campaign medal was changed in May 1945 to the 1939-1945 Star, the ribbon was already worn when the action takes place.

As the crippled plane makes a suicide dive at the tunnel mouth and the tunnel explodes a split second before the plane impacts.

When Scotty's plane crashes in the countryside, you can see the shadow of the plane model on the background scenery just before it explodes.

When Squadron Leader Munroe is driving along in the open top car, his lady passenger's locks of hair are perfectly still and not blowing around as would normally be the case in a speeding open saloon car. This scene is quite obviously shot inside the studio with a filmed background added. Usually a "wind" machine is used for the desired effect. Only very briefly when the couple are seen at a distance actually driving outside does the flowing hair appear normally.

Despite being raked with automatic fire at close range, the priest's white cassock shows no tears nor any blood-stains.

The tank at the end is clearly an American made Sherman with a Swastika crudely painted onto the front, not a German Panzer.

Before the titles, the cooling tower of a nuclear reactor is visible on the left-hand of the screen.

Despite the film taking place in WWII, McCallum still wears his "Beatle" haircut from "The Man From U.N.C.L.E." No RAF officer would have been permitted to allow his hair to grow that long.

When leaving their aircraft after missions, the aircrews are seen to have blackened cheeks - just like the World War 1 fighter pilots who returned from aerial combats bearing the same marks. However the airmen of the 1914-18 conflict received the facial smudges from cordite smoke that was blown backwards from the exposed breeches of machine guns mounted in front of the open cockpits of that era. The Mosquito had a closed cockpit and its forward-firing weapons were mounted in the nose - the gun breeches were not exposed, they were situated below the plywood floor of the cockpit and expended cartridge cases went through ejection ports. Mosquito pilots sometimes complained about feeling excessive vibration through their feet when firing long bursts with 20mm cannons, but never had to worry about streaked faces.

The German "Fighters" are in fact Messerschmitt Bf 108 four seat communication/Touring aircraft and are unarmed.

When the Mosquitos are filmed landing after the first training flight you can see a modern air park in the background containing Cessna's and the like.

During one of the air raids on the airfield a jeep skids to a halt on some grass, however the sound effect used is of wheels skidding on bitumen or tarmac.

In the garden scene when he is telling his family of Scotty's death, a microphone is visible at the bottom of the screen when the 2 men are talking in the arbor.
