W. Warren Wagar's A Short History of the Future is a memoir of postmodern times, cast as a history. This powerful and visionary book is narrated by a far-future historian, Peter Jensen, who leaves this account of the world from the 1990s to the opening of the twenty-third century as a gift to his granddaughter. A combination of fiction and scholarship, this third edition of Wagar's speculative history of the future alternates between descriptions of world events and intimate glimpses of his fictive historian's family into the first centuries of the new millennium."Thanks to Wagar's magisterial command of futurist information and theory, his extrapolated near-term future is an incisive, dynamic vision of where we may indeed be heading."—H. Bruce Franklin, Washington Post"A comprehensive, massively detailed script of a possible near future. . . . Intriguing."—San Francisco Chronicle"A Short History of the Future reads with ease, raises provocative possibilities and presents challenging occasions for thought and argument."—Chicago Tribune"A breathtaking future history in the manner of Wells and Stapledon, unnerving in its mixture of fact, fiction, and personal perspectives."—George Zebrowski, New York Review of Science Fiction

Warren Bodie's book is a marvel of completeness, including photos of all series and one-offs, and favorably presents what was arguably the best all-around fighter of World War Two. All the subjective criticisms of the famous Lockheed twin-boom plane are clearly discussed in their proper historical context, with ample support from the main historical actors. The book also demonstrates that the P-38, as a good child of Clarence "Kelly" Johnson's genius, was several years ahead of its time both in its technology and in the capacity of air strategists and pilots to fully exploit the advances it had over current aviation designs, as well as to foresee its potential. For example, the P-51 Mustang was a pig (and used the same Allison engine of the P-38) before being refitted with the famous Rolls-Royce Merlin engine which made it the masterpiece we know; just imagine a P-38 with two Merlins, something that never happened but that could have dramatically changed the air war before 1944 in all theaters. Bodie demonstrates that the P-38 was already the long-range fighter the Allies needed a couple of years before the P-51D and P-47N, but was stupidly underused and underdeveloped; its firepower was overwhelming and almost unparalleled throughout the war; it could turn with any enemy fighter and outrun most of them and, finally, having another engine was a priceless safeguard in the long flights over the Pacific Ocean and the Mediterranean. Highly recommended reading about my favorite fighter plane.
