Dan Mercer
Dan Mercer, retired air traffic controller with 35 years of service at Chicago O’Hare International Airport. After graduating from the FAA Academy in Oklahoma City in 1978, he guided thousands of aircraft safely through some of America’s busiest airspace. During his distinguished career, Dan received multiple commendations for his calm handling of several potential disaster scenarios, including a severe weather crisis in 1994 that required rerouting over 200 flights. A respected mentor who trained dozens of controllers, he now spends his time volunteering at aviation museums and occasionally guest lecturing at flight schools. “The sky never gave me a day’s work—it gave me a lifetime of purpose; every safe landing was my reward.”
