I am not a loadmaster.
In my opinion that loading method (shown in photos) is deeply flawed
solid wood blocks allow no compression and the blocks under the middle of the vehicle are supporting the solid structure of the vehicle and NOT able to compress (blocks under axles will allow compression by way of the vehicle suspension ) end result its possible to rock in pitch about the blocks set in the middle, possibly even enough to unlatch strap hook ends.
In my opinion the vehicle should have COMPLETELY deflated tyres and NO blocks, the straps and chains then attached to the vehicle compressing the vehicle suspension
I am not in any way saying this method was used in the crash flight or that if it was used, that it caused the crash, but (as a complete amateur in this field with no professional experience) I certainly dont agree with the securing method shown in those loading photos.
I still think the same
