META: Fan o' Planes
You need to get into contact with Ruby! Can you figure out their username? (Read the story here)
Note: This is a metapuzzle. To solve it, you'll need the puzzles from this round.
Let's go back and revisit those feeder puzzles! These schematics will provide you with the puzzle commonalities needed to group them into sets of three. Then maybe you'll be able to break up your three-part answers and, using these commonalities, reassemble them.
