Chrystal Gaye Stout was born on August 21, 1981, in Hillsville, Carroll County, Virginia. She was the daughter of Tony Stout and Julia Ann Shores. After graduating from Trinity Christian Academy in 1999, Chrystal attended Greenville Technical College and was later accepted to Liberty University. She also served as a Specialist (E-4) with the South Carolina Army National Guard. Assigned to the 151st Signal Battalion, 228th Signal Brigade, she deployed to Afghanistan in support of Operation Enduring Freedom and was stationed at Bagram Airfield.

On April 6, 2005, a U.S. Army CH-47D Chinook helicopter #88-00100, flying under the callsign “WINDY-25”, crashed near Khudaidad village, in Afghanistan's Ghazni Province, approximately 80 miles (130 km) southwest of Kabul. The aircraft belonged to Company F ("Big Windy") of the 159th Aviation Regiment, part of the 12th Aviation Brigade, which at the time was assigned to V Corps and based in Germany. WINDY-25 had departed on a routine resupply and passenger transport mission, carrying personnel and supplies between forward operating bases in eastern Afghanistan. The Chinook was transporting a mixed group consisting of Army soldiers, National Guard personnel, a Marine, Army Reserve personnel, and civilian contractors. As the helicopter approached the Ghazni area, it encountered a severe dust storm with winds exceeding 45 knots. These conditions created a "brownout" environment, in which blowing dust completely obscured visual references. During the flight, the pilots lost outside visibility and attempted to transition from visual flying to instrument flight procedures. Investigators later determined that the crew became spatially disoriented, meaning they could no longer accurately perceive the aircraft's attitude and movement. While attempting to regain control, the helicopter was over-controlled and ultimately crashed. All 18 people aboard were killed: five Army crewmembers and thirteen passengers. The aircraft was destroyed. Subsequent investigations found no evidence of enemy fire or hostile action; the accident was attributed entirely to the extreme weather conditions and the resulting loss of situational awareness.

Spc Stout was among the passengers aboard the aircraft and was killed in the crash. She is now buried in the Robinson Memorial Gardens, Easley, Pickens County, South Carolina, USA.
