The content of this book is the letter, official Top Secret U.S. Army Air Force interview transcripts and personal notes I received from the late Matilda O'Donnell MacElroy. Her letter to me asserts that this material is based on a series of interviews she conducted with an extraterrestrial being as part of her official duty as a nurse in the U.S. Army Air Force. The extraterrestrial she interviewed identified itself as an officer, pilot and engineer of The Domain Expeditionary Force, a race of beings who have been using the asteroid belt in our solar system as a intergalactic base of operations for the past 10,000 years. Her dying request was that the transcripts finally be released to the world. In a letter received with the transcripts, Mrs. MacElroy says: "Mankind needs to know the answers to questions which are contained in these documents: Who are we? Where did we come from? What is our purpose on Earth? If there is intelligent life elsewhere in the universe why have they not contacted us?
