 Mary and John are a married couple of airplanes. John, however, is an out of work B-29 bomber, but is trying desperately to find work, especially when it is discovered they are going to have a baby. John tries to get back in the Air Force, but they are only accepting jet planes now; something he despises, and something, he would soon discover, that his newborn son is. After reading about an around the world race among modern aircraft where the winner would receive a major government contract, John goes there determined to enter and show them up. Mary chases after him with Junior to try to talk him out of it. As she tries unsuccessfully to do so, Junior sneaks into his father for the ride, and by the time she realizes what he has done it s too late. When the race commences, the other planes are gone before John can even start taxiing down the runway. Eventually his props have had enough and detach from his body and leave him spiraling towards certain death. Junior manages to escape from him to save him and eventually lead him to victory. However, it is Junior the Air Force wants....and about a few hundred more just like him.
