While we're arguing minutiae...
the comment that keeps getting quoted that the plane was probably filled with light cardboard boxes keeps bugging me. Don't they box/pad/label at the distribution centers? I'd expect anything delivered by air to be packed a bit more efficiently
Boxed cargo will move by air 1 of 2 ways.
1) Palatalized and shrink-wrapped or cargo netted and secured to the floor
2) Inside air freight cargo containers that are built for that airframe.
I'd say #2 is most likely as those containers are designed for the plane they're going in to maximize volume related to the shape of the walls. These are also going to be far easier to secure to the floor with integrated latches and locks. Either way, every crate or pallet will be weighed and have a pre-determined location for the within the plane. This load plan will be followed to the letter by the load master.
Another thing to think about. There's no way to know the weight of each box. The plane was under contract to Amazon. You can buy anything you want/need for you life from Amazon. Much like FedEx, you could probably see a little bit of everything in those boxes. Everything from paper towels , laundry detergent, blu ray players, and brake discs.
