You can't expect him to be an expert at lightning as well. That's why Boeing has an EMI/Lightning group made up of experts in the field that support the various other disciplines so that they don't need to be EMI/Lightning experts.

Are you sure about the lack of copper in the 787 carbon fiber matrix? .
Thanks for the further comment about Tom.

Yes I'm sure about no mesh in the wing skins. I know mesh was seriously considered and I believe it was part of the planned configuration for some time, but I believe concerns about delaminations and difficult repairs after lightning attachments led to the decision to go without mesh.
