Starts off OK. Even the training section had possibilities. Once the doc savage stuff got going this turned into the biggest pile of doo doo I've ever read. I nearly passed out laughing when the protagonists survived a plane crash at sea and just so happened to find a false iceberg the size of a football pitch that his dad had built 90 years earlier. And it had a submarine!
Boy that was lucky.
Almost as lucky as learning how to fly a plane in his sleep, because that happens as well.
Shame I can't give zero stars
