Heather Penney  Heather Renee Penney (born September 18, 1974) is the director of United States Air Force Air Superiority at Lockheed Martin Aeronautics Company. She is best known for her role as a USAF lieutenant who was one of two pilots ordered to ram and down United Airlines Flight 93 before it reached Washington, DC, during the September 11, 2001, terrorist attacks. Heather Penney majored in literature at Purdue University. Her father was retired Air Force Col. John Penney (born 1947), who served from 1970 to 1979 during the Vietnam War and joined United Airlines in 1979 and served until his retirement in 2007. Penney was the "only woman in her fighter pilot training class and the only woman in her fighter squadron" (121st Fighter Squadron) with the DC Air National Guard, stationed at Joint Base Andrews. Penney, who was a first lieutenant at the time, was ordered into the air in her F-16 fighter jet alongside Marc H. Sasseville's aircraft at Andrews Air Force Base as the terrorist attacks were unfolding on September 11, 2001. They were ordered to down United Flight 93 before it reached Washington, D.C.'s airspace, but because of the urgency, there was not enough time to outfit their aircraft with live ammunition. The mission could only have been accomplished by ramming the plane with their respective fighter jets. Flight 93 subsequently crashed as passengers fought to take control of the aircraft. This ended the mission. When asked why she was ready to fly a kamikaze mission, Penney replied:  Why? Because there are things in this world that are more important than ourselves. Freedom. The Constitution of the United States. Our way of life. Mom, baseball, apple pie; these things and so many more that make us uniquely American. We belong to something greater than ourselves. As complex and diverse and discordant as it is, this thing, this idea called America, binds us together in citizenship and community and brotherhood. She served two tours of duty in the Iraq war. She currently works for Lockheed on the F-35 project. On September 7, 2017, Penney and her father, John Penney, gave a lecture titled 9/11 Perspectives at National Air and Space Museum as part of the GE Aviation Lecture Series.
