[EX Q]: Brilliant Thud memoire . The F-105 is a most fascinating aircraft. A superb cold-war design; it was meant to be a sort of man-guided supersonic cruise missile for delivery of nuclear weapons to tactical targets in the european theater. It was, of course, never used for this purpose, but was instead put to a use in the air war over Vietnam. The Thud was never meant to be a precision dive bomber, or to pass through heavily defended areas at subsonic speeds. All the same, politicians dictated this use (and of course went looking for someone besides themselves to blame when their "top fighter-bomber" started getting shot down in heroic quantity; so many were shot down, there weren't enough seasoned men to continue to fly them. They were shot down in so many myriads, fresh out of pilot school fighter-bomber jocks, or long grounded middle-aged desk jockies would be put directly into combat (where they would often be shot down).    The men who flew this jet were, as the cliche goes, a special breed of heroes. Unlike, say, fighter pilots or B-52 pilots, they faced almost certain death, or horrible imprisonment. Their survival rate was comparable to that of the B-17 tailgunner over Germany in WW-2; very low indeed. Oftentimes their missions were secret in nature, so the government couldn't even acknowledge that the Thud had been shot down and work for the release of the pilot.    Major Rasimus' memoire takes place at a crucial escalation in the war; in 1966. The Johnson administration decided to escalate the war by "sending messages" to the North Vietnamese via the use of bombing as a psychological and diplomatic tool. The hare-brained scheme was that, by bombing one thing, and not another, the NVA would be trained, like a pet dog is trained with a rolled up newspaper. The idea was ridiculous, and of course didn't work.     Rasimus was one of those unsung heroes who, fresh out of pilot school, grew enormous handlebar moustaches to protect them from evil on their impossible missions. He tells the tales of the base dog, Roscoe, and of various of his team, and those who came after. You can practically smell the oil on the tarmac, and the blackpowder charges which combat-started the '105's engines. While americans would rather forget the war in Vietnam, I can't forget the courage of these men who fought in these insane supersonic contraptions. May their spirit inspire a new generation of warriors. Thanks Ed; for your service and your great book

[EX Q]: Did a six year old write this? . This is the first Patterson novel I have ever read, and it is certain to be the last.  Most good authors draw the reader into a story by offering vivid descriptions and in-depth characters, but Patterson does none of that.  The author's writing style is akin to that of a small child's, as he uncermoniously plunks the reader in the middle of boring locales populated with one-dimensional characters.  Patterson then holds the reader's hand as he matter-of-factly recounts the explosion or gunshot du jour and then moves on without explanation, presenting a book written by a Ralph Wiggums-like child for immature children to enjoy.  How does the reader know Alex was scared? The reader knows because Patterson clumsily beats him about the head and shoulders with writing similar to the style: "The man pulled out a gun, Alex was scared, Alex shot the man and he was happy, and the man was dead."    Don't believe me? Simply graze through the book and find where the hero handily dispatches an arch-nemesis in a scene so brief and without fanfare I had to read it twice to make sure the protagonist killed who I thought he killed, or skip to the end if you prefer and painstakingly wind your way through a series of forgettable characters each deadpanning that he or she is responsible for the antagonist's evil deeds.    Quite simply, this author shows a complete lack of imagination and creativity and this book should be avoided at all costs
[EX A]: NEG

[EX Q]: Very disappointing unless you're in the (junior) target demographic . If you are a teenager or student in your early 20s and are fascinated with the big mysterious world of I-Banking, this book is for you. It starts from ground zero and provides a cursory explanation of what investment banking is, along with some guidance on career paths in the field.    If you are anyone else, forget it. As I struggled to maintain interest, I couldn't help but be reminded of a scene from the movie "Back to School", where Paxton Whitehead plays a B-school professor lecturing his class on how to start a business and Rodney Dangerfield plays a veteran businessman with no formal education. As Whitehead's character is pontificating about the nuances of how global interest rates affect the construction costs that a hypnothetical business will incur, Dangerfield's character can't help but blurt out "Why in the world would you build when you can rent in this market for half a buck a square foot and let someone else have the headaches of property management?". It quickly becomes apparent that the real-world experience of Dangerfield's character is far more useful than the off-topic theoretical knowledge of the professor. This author reminds me of Whitehead's character: Thoroughly vetted in academia and obviously having zero experience in the real world, and thus having zero useful real-world insight to share with his readers.    The most-cited references in the chapter bibliographies are the annual reports of the big I-banks, and the rest of the book is written at the same naieve, glossy-overview level.    In summary, if you want to know what it's like to serve in the Navy, you can get yourself a copy of the Navy's glossy brochure on what Navy careers are supposed to be like, or you can find a vet who's been in the Navy to tell you what it's really like. Reading this book is like reading the Navy's glossy brochure.
