Nope ... it wasn't Tweety Bird (of Looney Tunes fame) you saw flying around the local area. It was probably Phil Lumpkin (shown left below) flying in his bright yellow and white Sky Ranger, which he has named "Tweety Bird"    He even has a Tweety Bird painted on the tail (see center photo). Tweety Bird is now licensed as an Experimental Light Sport Aircraft (ELSA) with the FAA number N715PL.

Phil and his wife, Sonja, are originally from Maryland and moved to South Carolina in 2005. He is a retired police officer.
