I just realised that the Dorsal Anti-Collision Beacons were supposed to be light red, and not the 'normal' red that I had been setting them.
Fixed.

Changed light colour in cockpit - I just noticed that it was the wrong shade of purple. XD

Move the pilot's seat forward by 1 block to improve visibility, changed the block shapes around the nose and cockpit to aid getting out of the seat and replace armour lost by removing the block previously in front of the seat (including replacing the nose spotlight with a hardened steel block and a "spotlight mode" light).
