While Caitlin is flying the Santini Air chopper, fighting with Holly and being pursued by the military jets, the helicopter at one point is shown as having a different paint scheme and a camera mount on its left side. The registration number N2766Y, seen on its underside as it passes through a shot, confirms that it's a completely different vehicle. The Santini Air chopper's registry number is N2044C.
Despite firing off missiles, the F-15s have all their stores aboard after the helicopters left restricted airspace.
During the scene where Holly and Caitlin were in the Santini Air JetRanger the bottom of it was visible showing N2766y. But the Santini Air JetRanger is N2044c.
Dom is seen sitting in the helicopter while it is burning. He jumps out and a split-second later it explodes. He is then seen hundreds of feet away from it when Caitlin runs to him.
The Air Force air traffic controller tells his superior the approaching aircraft (Airwolf) is a helicopter. Unless the aircraft were hovering (which Airwolf was not doing) or had an active transponder (which Airwolf did not), there would be no way for the controller to know what type of aircraft it was.
The loose nut shown as coming off and causing a loss of control during the helicopter stunt scene would not have caused the control malfunction shown, as the threaded portion remained in place. The nut Caitlyn found and held up was also much larger than the one shown falling off the assembly.
At Holly's request, Caitlin is taking Holly up to String's cabin. However, they are flying over the ocean when the cabin is up in the mountains. There is no reason why Caitlin would be flying in the opposite direction over the ocean.
Mr. Santini states that the F-15s are using heat seeking missiles. The only missiles mounted upon the F-15s are Sparrow radar guided missiles.
When Caitlin stoops down to check on Dom after the explosion, her voice can be heard saying, "Dom, thank god!" but her lips do not move.
Dom says the planes behind them are F-14s. The Air Force never flew the F-14 Tomcat, only the Navy did. The planes depicted were F-15 Eagles.
The police officer tells Dom hours after the fire there were no mechanical causes for the helicopter fire. Local police do investigate crimes such as arson, however, aircraft incidents are investigated by the NTSB and take months not hours.
