I really enjoyed the first volume, but as I read this one something began to bother me. I couldn't put my finger on it until about page 108 when Cussler, or should I say Dirgo, details a friend's sense of humour.
The friend refuses to stow his bag on the plane, because it really isn't against FAA regulations not to. The flight attendant has to deal with this fellow, who Cussler tells us is an FAA investigator, and a retired Col. in the Air Force, as he refuses to do as she asks. She has to get the pilot to come and speak to this friend, who when faced with a "suitable" authority figure, has already stowed the bag.
Ho-ho! What a great joke.
Then it hit me, the whole book is filled with "We're so much smarter than everyone" episodes from the flight attendant to a 7/11 clerk. If you agree that Cussler and his friends are the pinnacles of human evolution, then this is the book for you.
I would recommend reading the historical chapters and skipping the rest.
