The Mystery of the Hot Air Balloon

My children have always enjoyed the Box Car Children series of books. As a hot air balloon pilot, we could not ignore a Box Car Children book with a balloon theme. I found the accuracy of the text to be very true and also a good source for children to learn about the sport of ballooning. I did some researce about the author and found that she died years before sport ballooning became popular. The "mystery" to me is "who wrote this book"? It must have been a balloon pilot or a balloon crew person. To find out what a balloon crew person does...read the book.
