Turbulence not necessary to explain LOC in this instance.
CB inadvertent penetration not necessary either.
Less than awake crew not necessary either.
Experience not an issue (test pilot experience maybe).
All of this an opinion, formed after extremely detailed and careful study (by several knowledgeable people). But then, it must be wrong, or else...
