"Flight of the Intruder" is a buddy movie about Navy pilots in the Vietnam War, circa 1972. It's a little darker than most buddy movies - the buddies keep having to be replaced when pilots are killed - and it has the germ of an idea to it. But it's a strangely disconnected movie that leads up to a point, makes it, and then drones on for another 45 minutes in increasingly witless cliches.
