#290. Jeff Thayer is a physicist, and back in the Space Shuttle days, studied and designed lightning defense systems for NASA to protect the Shuttle and other NASA rockets while they sat, vulnerable, tall metal objects on the launchpad in otherwise flat Florida. Jeff is also an avid sailor, and couldn't help but get in touch when he heard Andy talking about lightning on the podcast. Guest host August Sandberg dives deep with Jeff on the physics of lightning at sea in this very interesting and technical discussion.
