There was an accident in the waters off of Oceano airport yesterday. Not much information out yet, but the sheriff identified the pilot as David Casey of Friday Harbor, WA. His information matches dcasey1 from these forums: an RV-3 and RV-8 owner. At this point, I have no idea if this was an RV accident or not. They haven't recovered the plane yet.
