Shults was born Tammie Jo Bonnell and grew up on a ranch near Tularosa, New Mexico. As a child, she watched jet aircraft from nearby Holloman Air Force Base practice dogfights and maneuvers in the skies above her home. Watching these and reading about a missionary pilot, Nate Saint, inspired her to become a pilot too. During her final year of high school, she investigated the possibility of a career in flying but was told that there were no professional women pilots. Following high school graduation, she attended Mid-America Nazarene College where she earned degrees in biology and agribusiness, graduating in 1983. While at MidAmerica, she met a woman who had qualified as a pilot for the United States Air Force and decided to see if the Air Force would accept her application for service. After being turned down by the Air Force, she decided to try the Navy while doing graduate studies at Western New Mexico University.
After leaving the Navy, Shults joined Southwest Airlines as a pilot, flying a part-time schedule of 8–10 days per month so that she could also raise a family following her marriage to fellow naval aviator Dean Shults.
On April 17, 2018, while Shults was captain in command of Flight 1380 from New York to Dallas, an engine fan blade on the Boeing 737 failed and flying debris damaged the left side of the fuselage and one side window; the window failed, causing the plane to decompress. One passenger was partially sucked through the damaged window and was later pronounced dead at the hospital. Shults made an emergency descent and landed in Philadelphia. Her actions, calm demeanor, and competence during the emergency were noted by Southwest Airlines officials and passengers as well as Chesley Sullenberger, another commercial airline and former military pilot who controlled a similar situation in 2009 on US Airways Flight 1549. Shults later revealed that she had not intended to be the pilot of that flight, but had swapped the shift with her husband. Then-US Representative and former US Air ForceColonel and pilot Martha McSally introduced a resolution in Congress to honor Shults for her life-saving heroism and skill in landing her badly disabled aircraft.
Personal life
In 1994, she married Dean Shults, at the time a fellow naval aviator in the A-7 Corsair II, who also joined Southwest Airlines as a pilot that year. Together, they have two children. The couple lives in Boerne, Texas. Shults is a devout Christian who teaches Sunday school, and helps the needy, such as internally displaced persons from Hurricane Rita. Shults wrote a book about Southwest Airlines flight 1380, Nerves of Steel, which was released in the United States on October 8, 2019.
