Groundline — Live Airport Ramp Strategy Sim

Groundline is a live airport ramp you can play like a strategy game. An isometric terminal with a teal glass-vaulted roof sits beside a runway, with jet bridges, fuel tanks, baggage carts and service trucks moving around parked planes. A polished ops dashboard overlays it all: on-time departures, average turnaround, gates in use and bags handled, plus a flight list and a per-flight turnaround tracker from arrive to push back. @anxuanng says every plane and truck was modeled in Blender and runs in three.js, all built with Opus 5.5. It reads like a real product, not a tech demo.
