FYI, I'm in IBT Go-Team training in DC with NTSB and others, and Director of NTSB Office of Aviation Safety briefed us on this accident today. This is accurate info from NTSB source today:
The CVR/FDR on the accident aircraft stopped working on rotation; engine/fuselage/tail parts were located on the runway. A total of (7) MRAP armored vehicles were being carried as cargo. NAC was the only civil DoD contract carrier who will carry these vehicles. Aircraft loaded at Camp Bastian, not Bagram, was stopping in Bagram for fuel. Aircraft uplifted 48,000 lbs of fuel at Bargram for flight to DXB. After impact, 1 MRAP vehicle was deeper in the impact crater than any aircraft/fuselage parts.
