This was an American civilian 747 cargo plane that crashed at Bagram airfield in Afghanistan yesterday, possibly because the ascent angle was too great (stall) and/or the cargo broke loose and shifted back; the actual cause is under investigation.
All seven crew aboard were killed in the impact; condolences to the families.

Just… wow. You can see the moment where they were trying to compensate, and then they get pushed in that direction like a pendulum.
