He also previously served as Chief of the Flight Instrumentation and Flight Systems branches, and as project Chief Engineer for the F-18 Automated Aerial Refueling and the C-17 research flight computing system projects. For most of his 42-year career there he developed embedded digital systems for research aircraft ranging from an Army OV-1 propeller aircraft and a KC-135 tanker to supersonic fighters such as F-104 Starfighter, F-18 Hornet, and F-15 Eagle as well as SR-71 and TU-144LL supersonic high altitude aircraft. For 16 years Mr. Bever was the NASA representative to the NATO Advisory Group for Aerospace Research and Development (AGARD) Flight Test Techniques Group responsible for publications associated with flight test techniques and flight test instrumentation. Mr. Bever authored the AGARDograph publication "Digital Signal Conditioning for Flight Test." Between 1995 to 1999, Mr. Bever spent much of his time in Russia as the US instrumentation and on-site engineer for the TU-144LL high speed research project, which is the subject of this book. Although retired, Mr. Bever holds the position of Emeritus engineer at NASA Armstrong-the first person to hold an Emeritus position there.
