Congratulations, John. You got it right. One source states the Grob G 115 was first but that was ATC'd on 21 Dec. 1988. The Beech/Rutan original 2000 Starship beat that earlier by FAA certification in 14 June 1988. The 2000A Starship was certificated in April 1992.
This quiz started back in August 2011 and your recent attempts got it jump-started again, and I suspect my ballpark analogy was of help.
Again, Congrats to you!
