There are many internal chassis grounds in the plane itself...No idea as to what damage may've been done...I believe it's getting towed into a hangar dock this evening. We'll get a look at it in the next day or two. Some planes suffer very little internal damage from lightning hits, others it just screws their world up. We'll run PWIT (Primary Wiring Integrity Tests) from all points and see what's going on with it. They've got some pretty good redundancy/backup systems in them if in flight and anything happens.
