Astronauts Neil Armstrong, Jim Lovell, and Gene Cernan are among the most famous living Americans, and last night they were all getting on the same plane at Chicago O’Hare airport. This particular aircraft travels several thousand miles slower than they are used to, as it wasn’t heading to outer space. Instead, this American Airlines flight was going to Germany for the first stop on the “Legends of Aerospace” tour, where the innovative and inspirational aviators will share their life’s stories with our brave servicemen and women abroad. Armstrong, Lovell, and Cernan will be joined by the last Air Force Pilot Ace Steve Ritchie, SR-71 Chief Test Pilot Bob Gilliand, and former “Good Morning America” host David Hartman, who will serve as their emcee. These five airmen have inspired millions of Americans with their heroic efforts, yet they still seem to find themselves genuinely humbled by the opportunity to give something back to the country that has given them so much support over the years in their many endeavors. They also all seem to feel a strong bond with the troops they will be visiting, since like the troops, they used to put their lives on the line in the name of their country. Before they were allowed to take even ‘one small step’ onto the jet-way, though, they all had to show their boarding passes. I wonder if you need one of those to get on the space shuttle? In the video below, Armstrong, Lovell, Cernan and Ritchie tell us how excited they are about their big trip.
