It was local militairy UH-1. A local airforce pilot is flying out the abandoned aircraft to civilized place.
Getting the origiins / history of this
Bae-125 jet should be pretty easy,
Of course the XB-RCM registration is fake, but serial numbers everywhere.
Someone bought it into it's illegal status in the US. Where did it depart from? there must be a flight plan etc.
Also it's whereabouts before they pulled the transponder..
Intriguing un dated photo.. already with the fake registration. 
Just did quick research you can buy a flyable (dependent on requirements) 40 yr old 125 for $400k
