The Wikipedia page for SGI Dogfight contains the following unsourced claim:
In some intermediate version (between 1985 and 1995) aircraft inspired by Star Wars (X-wings, ...) were added. They disappeared in later versions.
Looking into this, I found that this claim was made in two edits from December 2015, by a now-deleted user.
The first of these read:
In some intermediate version (between 1985 and 1995) aircrafts inspired by Star Wars (Klingon, Xwings, ...) were added. They disappeared in later versions. The Klingon had unlimited speed and could not be stalled.
The second edit removed the references to "Klingon" (presumably a 3d model intended to resemble a Bird-of-Prey.)
I can't find any source that backs up this claim, and nowhere online does anyone mention sci-fi spacecraft as playable "planes" in dog/flight.
Does anyone know if it really was possible to play as sci-fi spacecraft in any version of the flight software? If you have evidence/screenshots/citable sources, these would be greatly appreciated.
(Although I realise very few people are likely to have a Silicon Graphics workstation sitting around, or to have had a chance to use one!)
