Since there's been some discussion of the use of wooden pallets, and since it seems to have escaped everyone that "wood" is just a word embracing a wide range of very different materials, may I ask what wood is used for pallet construction, what the spec is, and what controls are applied to bought-in pallets ?
First, the pallets themselves were not wood. The pallets were standard aluminum pallets.
The wood was used for weight distribution along the pallets, so the pallets didn't buckle so much as to prevent them from engaging the rail locks. The wood blocks were placed under various points on the hull and suspension so all the weight was not on the tires. I don't know what type of wood was used.
