At the beginning, as the squadron returns from a mission, a blue Land Rover can be seen in front of an airport building.
Land Rover began production in 1947.
During the final attack, one of the Mosquitos is shot down and crashes into a rock in the fjord and explodes.
Behind the explosion, the complete fuselage and tail flip unrealistically over the rock and onto the water When the "earthquake" bombs are being pulled in single file along a lane in preparation for the raid, a modern white hatchback (1964) is seen driving past the end of the lane in the background from left to right.
In the scene that show the special bombs convoy , you can see in the background two modern cars - looks like a Rover van - on the road.
Right at end of film, after the 'you cannot kill a squadron' speech, as the car drives away, there are 1960's fire tenders parked to the left of the shot.
The aircraft used to drop Erik Bergman over Norway is a genuine wartime B-25 Mitchell, but is wearing a silver and white color scheme typical of peacetime RAF transports and appears to have had its gun positions removed.
It seems unlikely that a brightly-colored aircraft with no defensive capabilities would have been chosen for such a mission.
When the Germans chase the resistance men in their lorry, the Germans armored car is actually a British Alvis Saracen, first produced in 1952.
The first view of enemy fighters is the 'kette' formations (only briefly seen high above) the lower of these 'stacked' kette formations are of three aircraft with noses apparently having the round cowling of Fw 190s.
The attacking "enemy aircraft" were obviously the wider body Messerschmitt Bf 108 which is first very apparent in one banking to attack a Mosquito near the first of the attack.
Even the vertical stabilizer shape shows it is not of a Bf 109.
The Bf 108 is further confirmed by the head on view showing the sport lightplane windshields.
The "gunfire" is flashing lights set into landing light positions flashing to simulate gunfire.
Two persons are even visible in the 108 cabin side-by-side.
There is also a center windshield divider separating the two windshield panels, not the flat bulletproof windshield of the 109.
These unmistakable facts are seen in the rear-projection shot of one hitting a Mosquito "head-on" in a scene.
The Mosquitoes used in the movie are of the B.
IX or XVI versions with bulged bomb bays to accommodate 4,000 lbs 'Cookies'.
The bombardiers' clear noses were painted over and a quartet of 'machine guns' (but not the four 20mm cannon) added to make the aircraft look like FB.
When the Norwegians are fighting from the cover of the crashed Opel truck the Germans are driving an Alvis Saracen personnel carrier.
This is both a British vehicle and a post war design that wasn't produced until 1952.
In 1944 with Germany under attack from all sides, Allies had air superiority over England day and night.
So a pair of Bf-108s from 1938-39 could not have attacked the base without having a dozen Spitfires chasing them.
One of the German armored cars used in the ambush scenes (the one that isn't the Alvis Saracen) is an obvious fake.
The gun barrel appears to be stuck onto the front of the turret, with no provision for changing elevation.
When the British airfield is attacked, the machine gun bullets come from a different direction than the flight path of the attacking German aircraft.
During the flight scenes inside the cockpit of the Mosquitoes, the rather large tails are notably absent in the view behind the pilots, showing that the cockpit scenes were filmed with a partial airframe, just the cockpit only.

The timing for me watching this is fortuitous, as just this morning I finished watching "Mosquito Squadron" (1969)--a very, very similar movie. Both films featured the de Havilland Mosquito (an amazingly fast and capable British fighter-bomber) and both were concerned with an Allied attempt to knock out a German rocket factory.
I've always enjoyed this film, ever since I saw it at the cinema in the sixties. The flying sequences are always thrilling and listening to those Merlins!
What utter garbage....every famous actor who was in it worth his salt probably denied ever being in it.
I used to love watching this movie when I was a kid. It is real Boys' Own stuff, just like those British booklet-sized war comics that Baby Boomers loved to read as boys.
633 Squadron is not too bad. The special effects are not that great though although seeing real Mosquitos is brilliant because there are none currently flying in Britain.
I was fortunate to watch this on its initial release in the summer of 1964 at the base theater in Wiesbaden, Germany. With a father a WWII medium bomber pilot (B-26 Marauder) it was especially significant.
The photography of real mosquitos flying is worth 9 stars alone. Only 2 left flying I think in world now.
I saw the film 633 squadron when it was first released in '64. The film follows in the tradition of many great Air War Stories including DAWN PATROL.
A true war movie classic that fits right in with the other ones (e.g.
