Video on crash 747

This video has now gone viral, showing clues on why crash 747 occurred in the first place. A plane can be used for many transportational needs, in this case the plane was carrying many 5 armored vehicles from Afghanistan. Each vehicles weighs 13 tons if they were to unchain itself it pushes back 20 or 30 tons to the back of the plane. This unbalances the plane causing it to crash, it is all about balance and double checking the attachments before taking off. We should all consider the efforts of those that allow us to travel places, especially when it is not just one person but hundreds of others that also add weight to the plane.
