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

Great book . Hiroshima by John Hersey is great book and I would recomend to anyone that they should read it.  Hiroshima is about the dropping of the first A-bomb on Hiroshima on August 6, 1945.  Tells true stories of several surivors from the moment of the bombing to their years after the bombing.  This book truly stands up to expectations of "Who is able to read, should read this book."  I think that everyone should read this book, not only for pleasure but for the true understanding of the Atomic bombing on Hiroshima through true stories told by people still alive today
