Question:-
What ships where on the wings demo on both sides?
I don't know about the trailer, but if the UA is inside a heavily guarded T9, then this is what we can expect:
had one convoy with a T9 holding Hafnium and other good stuff; guarded by 3 Anaconda's, 2 Dropships and 3 Vultures IIRC. Might be around the same for UAs. They didn't mind me scanning them.
I believe that UAs may be found inside both WSS and SSS. This fits with Redeyes experience and also these heavily guarded convoys carrying goods introduced in 1.2. I don't think Frontier would introduce anything that cannot be found / obtained by single players. Also, I don't think in order to find it you'd need any knowledge from the books/lore/forums, only in-game knowledge - which leads us to the article (am with Choccy here).
The GalNet article on weird science mentions AI, weapons and biomechanical enhancements. This kind-of fits the very rare salvage items introduced in 1.2 (Hafnium, AI Relics, and Unknown Artefacts). This suggests to me that the convoys carrying these goods are to be found around the old worlds (only). So, to find UA in a SSS, hunt around Lave.
Where to find UA in WSS is a different matter and Timocani seems to be one of the places where UAs spawn.
