New Leads On Plane Crash In Afghanistan

In this update, federal investigators know what brought down an overloaded plane in Afghanistan.

Michigan soldiers were on board.  

They say a military vehicle broke free, leading to a crash that killed seven crew members in 2013.

All but one were from Michigan.

The National Transportation Safety Board says there was a vehicle on board that wasn't secured properly.

It crashed through the bulkhead and disabled two hydraulic systems.

That made the aircraft uncontrollable.

It crashed just after takeoff.
