Update Notes for 1 Aug 2025 — Terminal One Steam update #526469

Gameplay: Added two new aircraft (one size 1 and one size 2). Gameplay: Added three new airlines. Policies: Added Allow Supersonic Jets policy. Supersonic Jets have low passenger capacity but bring a high base income. They can help a player earn extra income in the early game. However, Supersonic Jets also have a high carbon cost, making it challenging to sustain them in the later game. One other difference of Supersonic Jets is that they require a Ground Power Unit (this is dispatched automatically from a connected cargo depot, regardless of the chosen Ground Power Unit policy). Sound: Added more voices for pilots and cabin crew speech when arriving and leaving stands, arriving at runways, and departing.
