 CONT: The helicopter in the night patrol scene switches between two  distinctly different makes and models. When Deputy Commissioner Mark  Halpern goes on helicopter patrol, his helicopter actually changes  type twice during the flight. First we see a Bell 206 JetRanger,  which then turns into a Hughes 369 before reverting back to the Bell  206. Commissioner Halpern is then seen climbing out of the Hughes  369 to drag his wifes body out of the pool. The two helicopters are  very different, even to the untrained eye.
