On April 10, 2010, Polish Air Force 101 (roughly equivalent to the U.S. government Air Force One) carrying the Polish President, first lady, and 94 other high level government officials, clergy, military, representatives of Katyn Families, and other important individuals in Poland's business and culture crashed in a fog outside of Smolensk, Russia. The plane was on its way to a ceremony to commemorate the 70th anniversary of the Katyn Massacre. There were no survivors. This book describes what happened and why. It points out the complex nature of such tragic plane crashes often due to human factors. More importantly, it tells the story from the perspective of the people involved and the terrible loss to the country which resulted from this historical and tragic event.
