On this edition of Airwaves, Russell, Hamilton, and Evan ask a question about how and why runways are numbered and designed, discuss what the phonetic alphabet is and how it relates to aviation and communications with ATC, dive into some news stories regarding female pilots and future supersonic jet projects, and tell a couple of stories about just how tight-knit our aviation community actually is.
