No. You only got access if you took on the Agent's Quest missions. You had to go find Mic Turner's ship, the Turner's Quest at Pleione 4b. After a bit of a set too with INRA/Feds you could get the flight recorder. If you took that back to the Alliance they looked at it and found the Turner had found a Thargoid shuttle at Polaris. You could then take on the mission to go there. Of course INRA/Fed goons had a had occupied the system.
I never did these mission so this is all from wikis and work of mouth.
Of course Michael Brooks said that timeline never existed in ED but I might go have a poke around Pleione 4b anyway.
There where four 'Quest' ships produced. Turner's Quest, Argent's Quest and two others. I do wonder if these are, in the new world the Manticore class that some Fighter Pilots talk about. I would happily help the Turner's out bu flying one for Alliance interests, after my years of service. In fact, I am out near the Turner bases in the California Nebula right now, to see if they are in range of a friendly takeover of the Asteroid base out there.
Thargoid tech in that tail anybody?
