747-400 Crash @ Bagram

40+ years ago a Navy C-2 stalled and crashed after launching from USS Ranger (CVA-61). Cargo shift was blamed for that accident and if you compare the video with the Bagram crash they're very similar.

 
Dreadful to watch and seeing such a large aircraft tumble out of the sky in that way .After the video I guessed cargo falling to the rear of the aircraft.
 
The 74 was carrying 5 MRAP vehicles @ 14+ tons. There are reports that one of the pilots called Mayday just after the apparent pitch up saying they had a load shift on rotation. MRAP"s being heavy as they are, one breaking loose would've done it.
 
Yep, that was my guess as soon as I saw it's attitude and the news said it was a cargo flight. Not a normal take off attitude at all.
 
Having Hauled a lot of the MRAPS in and out of Afganistan, they are pretty healthy machines. Load breaking loose is the most likely. They are usually pretty well secured, but the military uses a different system than the civilian counterparts. Possible is failure of some components, whether part of the floor system or the tie downs.

The aircraft was climbing way too steeply, a phase where I expect all effort was being made to reduce the AOA. The plane finally rolls off, it may be that this was an intentional recovery attempt, a little more altitude and they would have made it. That makes three 400 freighters lost with their crews in the last several years, all possibly due to load issues, whether fire or shift.

My heartfelt condolences to the relatives and friends of the crew!

If the load was military vehicles and a heavy truck or AFV broke loose, the sudden weight shift would cause the plane to pitch backwards suddenly with no chance of recovery, porbably not even at altitude.
 
It is painful to watch.

Shifting cargo is, sadly, neither new nor confined to large military vehicles/equipment:

13 FEB 1956 -- The Bristol 170 crashed soon after takeoff into the sea, 1,5 miles offshore. The aircraft was on a cargo flight to the Distant Early Warning (DEW) radar line. -- PROBABLE CAUSE: "Loss of control due to improperly secured heavy cargo breaking loose and sliding to the rear of the aircraft during takeoff."

20 NOV 1977 -- (another Bristol Freighter) - The aircraft stalled in a nearly vertical attitude at 200 feet height, pitched nose down and crashed.
PROBABLE CAUSE: Shifting of a load of corrugated sheet steel.

A search of accident databases shows too many others.

Unlikely as it may seem, there have been numerous CofG errors in loading/mgmt, some of which are similar
