Skyjacked

Five teenagers from the elite Hartwell Academy are on their way back to New York from an end-of-summer camping trip in Idaho when they realize that something has gone wrong; one of them has become violently ill, and their private plane has apparently been hijacked and is headed in the wrong direction--and even if they can somehow break into the cockpit and manage to overpower the hijacker, they have no idea how to fly the plane, much less land it.
