Antonio built his airplane (N289AE) with the help of x-jets. The first flight was successful, but the second flight landed short of the runway (accident), apparently because the pilot got behind the power curve and couldn't get the engine to come up to power quickly enough on approach.
The aircraft flew again in 2009.
Tragically Antonio was killed in a crash of his Beech 98 in March of 2010. His plane was auctioned on eBay in 2014.
Any information on this Jet are welcome !
