Never Retreat (5)

"What do you mean, it was the wrong flight plan?! We've been flying for eight hours now, and you're telling me it's wrong?!" He Zhichu was so angry, he pounded the wall. Glaring at the co-pilot, his eyes were about to spurt flames.

The co-pilot cried out, "We… We also don't know what happened. Everything was normal. If we really had been on the wrong flight plan, then the aviation control towers on the ground would have warned us a long time ago. But they didn't… We've been communicating with them the entire time, and they said everything was normal."

The ground-level aviation control towers of all the countries were used for radar tracking of aircraft passing through their airspace. Normally, flight plans were announced beforehand, and if a flight plan wasn't previously announced, the aircraft would receive an emergency warning. In serious cases, it was considered an invasion of airspace and met with prompt destruction.
