Originally published 1930. This is the first book of the Sky Buddies, Jim Austin and Bob Caldwell and their plane, properly christened "HER HIGHNESS" in which they encounter many thrilling and exciting adventures.
Teenage stepbrothers, with their own plane, fly up to Vermont near the Canadian border to visit their aunt and uncle who raise turkeys. They soon are involved in three mysteries: helping the Canadian police stop smugglers crossing the border, trying to stop the theft of a large portion of their uncle's turkeys, and figuring out the mysterious boy and his uncle who are helping out on the farm. Of course there are other adventures of helping an airmail pilot deliver his important cargo and helping rescue people during a dangerous flood.
Plenty of adventure. A fun book to read. I love it when someone of another race says that Americans are clearly inferior. Turns around the typical stereotype and prejudice.
