This old Airbus A319 version 115X from the year 2006 is announced to belong to Aviation Horizons, which is a Saudi based aviation consultant company registered in Jeddah. As is apparent from the picture, the machine lacks one engine and it still has its previous owner's registration markings. As new it was delivered to China Sonangol in 2006 where it stayed a bit over one year. Then it went over to Sonair of Angola where it was used again for a bit over one year and then it was just stored in October 2008. It was registered to White of Portugal in February 2011 and it has been owned by Aviation Horizons already from April 2016, but apparently it has never flown and has never been registered. It's also interesting that Aviation Horizons does not mention it in their "list of fleet" which currently comprises only one 20 years old B737.
