Known as "The X-Hunters," authors Peter W. Merlin and Tony Moore have located more than 100 crash sites of exotic aircraft from Edwards Air Force Base and Area 51. Together, they have recovered parts of supersonic rocket planes, stealthy spy craft, and vehicles that have reached the edge of space. Each story in the book profiles an unusual aircraft and the brave men who flew it. The authors examine the contributing causes of each crash and use then-and-now photographs to illustrate their findings. The stories end with The X-Hunters' search for the crash site and what they discovered. Each adventure combines C.S.I.-type skills with X-Files persistence, with a dash of Indiana Jones for adventure. Aircraft profiled include the YB-49 and a pair of N9M flying wings, X-1A, X-1D, VB-51, XB-70, SR-71, YF-12, U-2 prototype, and many more.
