Investigating the disappearance of an air taxi pilot, Frank and Joe uncover evidence of sabotage that points directly to the missing man's passenger, millionaire Ian Fairbanks, who is connected to a national conspiracy.
Franklin W. Dixon is the pen name used by a variety of different authors who were part of a team that wrote The Hardy Boys novels for the Stratemeyer Syndicate (now owned by Simon & Schuster). Dixon was also the writer attributed for the Ted Scott Flying Stories series, published by Grosset & Dunlap. Canadian author Leslie McFarlane is believed to have written the first sixteen Hardy Boys books, but worked to a detailed plot and character outline for each story. The outlines are believed to have originated with Edward Stratemeyer, with later books outlined by his daughters Edna C. Squier and Harriet Stratemeyer Adams. Edward and Harriet also edited all books in the series through the mid-1960s. Other writers of the original books include MacFarlane's wife Amy, John Button, Andrew E. Svenson, and Adams herself; most of the outlines were done by Adams and Svenson. A number of other writers and editors were recruited to revise the outlines and update the texts in line with a more modern sensibility, starting in the late 1950s. The principal author for the Ted Scott books was John W. Duffield.
Overall this was a great book! It was boring through the middle, but it started picking up towards the middle. Great ending thought! Would recommend to any mystery lovers!
Despite my enthusiastic 10/10 review from the time I read it, I think in the grander scheme of things it was more like a 4/5. ;) Here's my review from the time:
"The Hypersonic Secret is a really exciting book. It's about Jamal Hawkins' dad disappearing in a plane crash. The Hawkins Air Service chartered Ian Fairbanks to Ottawa. The plane crashed in the Adirondacks, and the people aboard weren't heard from. Jamal asked Frank and Joe Hardy to solve the case. They come against many obstacles, such as sabotage. In one part, they're flying a Cessna airplane. Ice forms on the propeller, and the carb-heat will not work. They crash in the Atlantic Ocean and are rescued by the Coast Guard. Who is trying to kill Jamal, his dad, Frank and Joe? I can't tell you, because that would spoil the story!"
What I find hilarious about this story is that I come across aircraft-related documents in my work... this was secretly preparing me for my future. :P
This was a good tale, but not one of the better books. It dragged just a bit too much in the middle.
Gone for this adventure is Chet Morton to be replaced by Jamal Hawkins. Jamal is a fellow teen in Bayport whose missing father starts the mystery. The villains are certainly villainous and even threaten to shoot the Hardys and toss them out of an airplane.
Pick up the book for your sons or nephews or read it for yourself and then give it to them.
