Americans Among Those Killed in Germanwings Plane Crash

Two Americans were aboard the Germanwings Flight 4U 9525 that crashed into a remote area of the French Alps on Tuesday, killing all 150 passengers and crew on board.

Germanwings CEO Thomas Winkelmann told reporters that two Americans were aboard the flight that reportedly lost altitude before crashing into the mountainside at around 10:50 a.m. Tuesday morning. The U.S. State Department has yet to confirm the deaths of the two Americans.

According to "Good Morning America," there were also 72 Germans, 35 Spanish, as well as passengers from Australia, Argentina, Iran, Venezuela, Britain, the Netherlands, Colombia, Mexico, Japan, Denmark, Belgium and Israel on the plane.

Officials have indicated that there are no survivors of the firey mountainside crash, and have suggested that they are still determining the nationalities of all plane passengers, as some may have carried dual citizenship.

Authorities have said that they will now focus on an analysis of the plane's black box to determine the aircraft's final minutes before it went crashing into the French Alps in a remote area dotted with small villages and near a popular ski resort.

According to NPR, French Interior Minister Bernard Cazeneuve indicated that it is unlikely the Germanwings plane was blown up, a theory some have attributed to its sudden crash.

"Every theory must be considered while the inquiry goes on," he told reporters. "An explosion is not the No. 1 suspected cause because the debris from the plane is concentrated in an area of about 1 1/2 hectares. It's certainly a wide area because of the violence of the impact, but it shows that the plane probably didn't blow up."
