Tom Swift and His Sky Racer: The Quickest Flight on Record

Tom enters an air race with a prize of $10,000 and designs and builds a speedy 2-seat monoplane, the Hummingbird. The plans for it go missing after prowlers are spotted. An assault on Tom, a fire, and overwork all combine to cause Barton to have a heart attack. Tom's new plane is used to summon distant medical help for his father. It's up to Tom to find the plans and win the big race (Unofficial Home Page).
