When Airwolf approaches the farm complex it's hovering 10 miles away looking at the farmhouse. The shots from the farmhouse are nighttime shots, while the ones of Airwolf are in broad daylight.
The refueling tanker has a refueling probe. Since the Airwolf has a refueling probe, the tanker should be trailing a drogue, for a refueling probe cannot mate with a refueling probe.
Helicopters that can normally refuel in mid-flight have an extending boom that docks with a Drogue, Airwolf has a refuelling boom that is only a few feet long, using this would surely catch the rotor blades on the hose coming from the refuel aircraft.
When Airwolf meets up with the refueling tanker, there is a shot of Airwolf getting closer with its refueling nozzle. Airwolf's pilot is wearing sunglasses and not the normal Airwolf helmet. Stringfellow would never fly Airwolf with just his glasses on - he always wore the helmet.
When Airwolf first lands at the cabin, there are 2 shots of Jan Michael Vincent running towards it. In the background is a Hughes 369, not Airwolf.
When the Russian is singing in the kitchen, his mouth does not match the words, nor does his fingering and picking of the lute match the music.
After Airwolf dives to a very low altitude to lose the MIG-23s, it flies over some cows and a house. At the house, you can see the helicopter's right skid. Airwolf doesn't have skids.
