What is this jetliner seen in the Falcon Crest TV series?
It is a Grumman Gulfstream II business jet, not an airliner.
The oval windows are very unique to both the Grumman Gulfstream I business turboprop, and Grumman Gulfstream II business jet. The small engines are Rolls Royce &quot;Spey&quot; engines meaning it is either a Grumman Gulfstream II or Gulfstream III. (later Gulfstream versions had the larger &quot;Tay&quot; engines) The lack of wing tip &quot;winglets&quot; means it is has to be a Grumman Gulfstream II.
