What's in the hanger behind VSZ in the last pic?

Looks like it is a Cessna 750 Citation X going by the size of the engines and the tail. Strike that!

Well taking a closer look, it is a Bombardier BD-700 Global Express or Gulfstream G650. The shape of the thrust reverser is the give away. Citation X is totally different

Legacy?

Hello Gentlemen,

The aircraft in the hangar is Embraer ERJ-135BJ Legacy N898JS. It has been in that hangar being worked on for a very long time and at one stage even had the registration taken off.

Regards

P.S According to Flight Aware it landed in Sydney 10 weeks ago which sounds about right

Well, at least it's not M-ATAR! That's finally gone to the States to find a buyer.
