This book opens the door to a lost chapter of aviation history, and to a secret royal thank you that was hidden for almost eighty years.  It follows Larry Bell, founder of Bell Aircraft, as he builds the P-39 Aira Cobra for Britain during World War II, helps spark America's first jet program, and earns the personal gratitude of King George VI and Queen Elizabeth.  Two rare airplane brooches, made in precious metal and stones, were created for him by royal order.  These gems are not only jewelry, they are keys, and once you see what they unlock, you will never look at the story of World War II in the same way again.
