I went t visit an uncle in Tucson AZ. and from his place you could hear and see the A-10's taking off from Davis–Monthan Air Force Base. I could have sat on his porch all day and watched that. They're one of those planes that have a distinct sound to them.
Why not ask the source? I think there might be standards within the lumber industry. I think members adhere. For me the only time the rough wood ends up too thin is when it is crooked and takes a lot of work on the jointer and planer to flatten it.
