Your comments made me wonder if there were height restrictions, found this verbiage on US Airforce site:
"For pilot and aircrew positions, height specifications vary by aircraft and most applicants can successfully pursue a career in aviation with the U.S. Air Force. Applicants who are significantly taller or shorter than average may require special screening to ensure they can safely perform operational duties. Applicants of all heights are encouraged to apply."
