Wildfire Incident Response

Replay

Fault runs

Scripted runs over the recorded feeds: a fault is injected at one step and a scripted operator tries to approve through the same checks the console uses.

Lost resource feed

Aspen Acres · set 2026-09-26-r2

The simulated AVL feed of engine, crew and helicopter positions drops out, then comes back.

The fault is simulated; the snapshot, briefing and decision checks are the real code.
