The fourth entry in the Iron Eagle series follows the return of General Charles "Chappy" Sinclair (Louis Gosset Jr., who deserves better) as he trains a Dirty Dozen-style team of juvenile delinquents to improve their quality of life by flying planes and combatting evil. This time the Air Force itself is the enemy, as the intrepid teens uncover a conspiracy involving biological weaponry. When Chappy contacts his old friend, General Kettle (Al Waxman), he learns the General is in on the action. Along the way, the group manages to combat some ill-prepared drug dealers as well. This installment is better than the second or third, but that's not the highest of praise; Iron Eagle IV is a dumb-dumb fantasy for fourteen-year-old boys who don't yet have their learner's permits, much less their pilot's licenses.
