This book opens the door ro 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 Airacobra for Britain during World War II.  He earned 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.  They vanished into a secure vault. These gems are not only jewelry, they are keys. And once you see what they unlock, you will never look at World War II the same again.
