The "Extras" are pilots from a private equity-owned intergalactic conglomerate achieving capitalistic synergies through acquisition of more assets than needed, desired, or required; in order to better withstand macro-economic headwinds.
Although infused in countless industries, Extra Corporation is perhaps, best known for producing enhanced pilots of extraordinary capability with less reliance on weighty flight automation, saving their clients billions in credits each fiscal reporting cycle.

Disclaimer: Extra Corporation and its affiliates are a satirical take on the imagined business practices of the year 3303.
No actual corporations (and only a few Cmdrs.) were harmed in the making of this parody.
