Old School action movie with terrific acting. Roy Scheider is brilliant as the PTSD suffering Vietnam pilot. He overcomes his demons in a good cause to save the public from sick government corruption which intends to use the advanced helicopter for crowd control and armed insurrection. The government agents are deliberately stirring up trouble in the streets just to create an opportunity to show off the new helicopter's firepower on innocent civilians. This movie has air battles, police chases, and non stop action to the end. Malcolm Mcdowell is wonderfully brilliant as the main opposition and Warren Oats delivers his usual gritty performance reminiscent of "Bring me the head of Alfredo Garcia". The dispatcher voice in the movie is Shaaron Claridge who also was the dispatcher voice in "Adam-12" A blockbuster from long ago .
