When Disco is loading three ships appear, a medium sized one, a large one (both with orange/brown exhaust) followed by a smallish one, anyone know what they are called?
There are multiple opening scenes, but I know the one you're talking about.
The big one is a Redemption Battleship.
The three small ships are Basilisk bombers and an Agama heavy fighter.
The medium ship is a Perilous Gunboat.
They're council ships, from gallia.
They are being replaced in 4.86 with floating debris.
There should be more of those little videos playing in the background and FL will pick a random one upon starting the game and opening the main menu.
