You’ll also need to be a pilot with at least 1,000 hours of flying experience in a high performance aircraft like a fighter jet, or have a PhD in a subject like biology, chemistry, engineering, information technology, mathematics, or physics. With either of these routes, you’ll usually need 3 years’ experience.
