Claim of Privilege: A Mysterious Plane Crash, a Landmark Supreme Court Case, and the Rise of State Secretsby Barry Siegel
On October 6, 1948, a U.S. Air Force B-29 Superfortress crashed soon after takeoff, killing three civilian engineers and six crew members. In June 1949, the engineers' widows filed suit against the government, determined to find out what exactly had happened to their husbands and why the three civilians had been on board the airplane in the first place. But it was the dawn of the Cold War and the Air Force refused to hand over any documents, claiming they contained classified information. The legal battle ultimately reached the Supreme Court, which in 1953 handed down a landmark decision that would, in later years, enable the government to conceal gross negligence and misconduct, block troublesome litigation, and detain criminal suspects without due-process protections. Claim of Privilege is a mesmerizing true account of a shameful incident and its lasting impact on our nation--the gripping story of a courageous fight to right a past wrong and a powerful indictment of governmental abuse in the name of national security.
