(From the wsj.com) The U.S. military didn’t always bring home its dead. In the Seminole Indian Wars in the early 1800s, most of the troops were buried near where they fell. The remains of some dead officers were collected and sent back to their families, but only if the men’s relatives paid all of the costs. Families had to buy and ship a leaded coffin to a designated military quartermaster, and after the body had been disinterred, they had to cover the costs of bringing the coffin home.

Today, air crews have flown the remains of more than 5,000 dead troops back to the U.S. since the conflicts in Iraq and Afghanistan began.

For those charged with bringing out the dead, it is one of the military’s most emotionally taxing missions. The men and women of the Air Force’s Air Mobility Command function as the nation’s pallbearers, ferrying flag-draped remains to Dover Air Force Base in Delaware from battlefields half a world away.

The missions take a heavy toll on the air crews, but many of the pilots and loadmasters say their work is part of a sacred military obligation to fallen troops and their families. Air Force Capt. Tenaya Humphrey was a young girl when her father, Maj. Zenon Goc, died in a military plane crash in Texas in 1992. She remembers his body being flown to Dover before his burial in Colorado.
