Former private first class Jessica Lynch, who was rescued by U.S. Marines on April 1, 2003, from a hospital in Nasiriyah, Iraq, became the first POW to return home from the Iraq War.  Lynch was captured by Iraqi forces after an ambush on her convoy on March 23, 2003.  After receiving a tip from an Iraqi civilian, U.S. forces launched a nighttime raid on the hospital, rescuing Lynch and recovering the bodies of eight American soldiers.

Former U.S. Air Force fighter pilot Scott O'Grady evaded capture when his F-16 was shot down over Bosnia in June 1995 by a Soviet-made SA-6 mobile missile.  After surviving for six days by eating leaves, grass and ants, O'Grady was rescued by U.S. Marines of the 24th Marine Expeditionary Unit.

The Joint POW-MIA Accounting Command found the remains of missing U.S. soldier Don Grella in April 2009 after nearly 44 years of searching for Grella, whose Army helicopter went down in a dense jungle on Dec. 28, 1965, near An Khe, Vietnam. (www.virtualwall.org )

Michael "Scott" Speicher, the F/A-18 "Hornet" pilot who was shot down over Iraq on the opening night of Operation Desert Storm in January 1991. The Pentagon initially declared him killed, but uncertainty led officials over the years to change his official status a number of times to "missing in action" and "missing-captured."  The Pentagon said the Armed Forces Institute of Pathology on Saturday positively identified Speicher's remains, buried in the desert and located after officials received new information from an Iraqi citizen about a crash.
