What is this aircraft on the grass in Budapest International Airport? While taxiing after landing in BUD recently, I noticed a widebody aircraft half-hidden in the trees on the grass of the airport. You can see it on Google Maps over here. 

What is this aircraft, and why is it positioned like that? There’s the fire brigade building nearby, but they already have a training aircraft a lot nearer.

It has the distinct shape of the 767, and it is indeed a 767 (registration HA-LHB, ex Malev) as can be seen in these photos:

By the state of the airframe (and the fact that it is illuminated) it is indeed looks like it is being used as a firefighting/rescue training frame.
