Is this list for him, or is really for you? =P
Joking aside, tell him about Joseph Kittenger and Felix Baumgartner. Kittenger was the pilot/sky diver involved in Project Excelsior. The highest/longest sky dive in history. 15 minutes of free fall. Felix Baumgartner is a dare-devil currently trying to break that record. He's being sponsered/supported by Red Bull (come on, thats instant cool), and Kittenger is consulting on the whole thing. If all goes to plan Baumgartner will break the sound barrier. With his body.
If he wants famous aircraft designers, two giants that come to mind are Ben Rich and Kelly Johnson, both of Lockheed Skunkworks fame. Unfortunately, they're both gone from this world... the days of airplanes being a single person's brain child is quickly faming (if not gone). If you wants some famous pilots, probably the single most important pilot would be John Boyd. One of the best fighter pilots ever, he also went ahead and pushed an entire generation of air force fighters into service, developed an entire engineering metric on comparing the performance of fighters, and then went ahead and revolutionized the way we fight wars (look up Maneuver warfare... all of the official doctrines of the armed services are based on his ideas).
