This CNN link below is an update on the National Cargo Boeing 747-400F that crashed at Bagram Air Base, Afghanistan back in February 2013. In my opinion, I was concerned that this might have been the cause of pilot error, or human error. There speculating that the straps might have broken off holding the tanks and vehicles inside the plane and caused an imbalance and disturbed the center of gravity. This is according to the Afghan Civil Aviation Administration, however Im certain that officials from the NTSB, Boeing, and the FAA are also investigating the cockpit voice recorder and the data video recorder (black box). The investigation is still not 100% complete and is still pending. But this is good progress thus far.
