Come on people, this movie was made 37 years ago. Air war was the reality of military conflict so it was only right that Hollywood reflected that. Now its all desert war movies because that's where the potential threat comes from these days.
The aircraft footage you just don't see anymore, the only other movie that did was Top Gun, and it grossed a ridiculous amount of money. This movie has that old movie feel because of the actor lineup, Kirk Douglas is old school. So watch this movie not for the special effects but for the Sci Fi possibility aspect. It was 1980, come on, give it a break.
If you are into military aircraft, this movie will float your boat.
