- — Tagline, from the front cover
Frank's old friend Ray Adamec, former ace navy pilot, has been hired to test pilot a superhot, supersleek jet -- the MAX 1. But then Ray disappears, and the MAX 1 is nowhere to be found. Frank's pilot license proves invaluable as the Hardys take control of the MAX 2. Their mission: find Ray and recover the MAX 1 before it falls into dangerous hands.
Finding a clue to the whereabouts of the MAX 1 in the Utah desert, the boys set out to investigate. Instead they find themselves outnumbered and outgunned in a high-tech, high-altitude air battle. They've flown into the middle of a subversive plot posing a deadly threat to the top levels of the U.S. space program and the U.S. government!
