In my travels recently I ran across this rather interesting bird: N504EA, the third Eclipse 500 prototype airplane tethered behind a hangar at Double Eagle II in Albuquerque (KAEG). A short few years ago this airplane was the pride of the Eclipse fleet, a flight test prototype found in PR photos on many websites. 504EA was responsible for a lot of the testing that culminated in a type certificate for the Eclipse 500 fleet. Eclipse Aviation went bankrupt in early 2009 but the company is now emerging from ashes as Eclipse Aerospace in Albuquerque. Good luck, Eclipse!
