I have just finished the book. It is boring, and it isn't even well developed. Many parts are very unrealistic. I've seen this kind of situation on TV or in movies. Very disappointing!!!! My other half who reads all sorts has said she enjoyed it...but I'm afraid we don't agree about this. She says there were many holes here to fill that weren't there.. We both like mystery stories, which this book was, but a lot happened, then nothing happened.

First thing I want to say is that it isn't a "high end" product, like some have stated. But for the price. It just worked great with my Nexus 10. Just make sure you plug in your USB power source. My only complaint would be that because of its length, when using a cover on it. The cord will sometimes get twisted inside and not charge. Other than that, it works quite well!Thanks,Joe M

The book seems to be well put together and is great for quick reference. However, I need a book like this in order to plan my journey from the point of view of someone who travels constantly as an engineer or technical consultant. There are several things missing that would have improved this book, including:- More detailed information on the history of aviation (pre & post war)- Less focus on aircraft manufacturers- Inclusion of some maps detailing routes across country with specific stops along those routes.
