Air Traffic Controller
Air traffic controllers perform their duties behind the scenes. They do not have the fancy pilot suits or hand out little wings to children. However, they are important people to thank every time your plane arrives safely.
Besides, if you do get famous, it's highly likely that you don't want to be—remember the guy who had his 9-year-old son give taxi directions at JFK? Yeah. Now he’s driving a taxi to JFK. No JK.
