President Barack Obama and top Pentagon officials are attending Tuesday's dignified transfer ceremony for 38 U.S. and Afghan personnel killed on board a helicopter shot down in Afghanistan over the weekend.
Two planes carrying the remains landed at Dover Air Force Base in Delaware on Tuesday morning, according to Pentagon spokesman Col. Dave Lapan.
Because the catastrophic nature of the crash made the remains difficult to identify, all were brought in more than 38 transfer cases to the United States, Lapan said. The Afghan remains will be returned to their families once identifications can be made.
The slain U.S. service members represent the worst single-incident loss of American life since the start of the Afghan war.
Thirty Americans died in the crash, including 22 Navy SEALs, military officials said.
