Soldier: Quite a sight, wasn’t it Sir?

Col. Edwards: A sight I’d rather not be seeing.

Soldier: Are you worried about them, Sir?

Col. Edwards: Well, they must have a reason for their visits.

Soldier: Visits? Well that would indicate visitors! Are big guns the usual way of welcoming visitors?

Col. Edwards: We haven’t always fired at them.

Soldier: Oh?

Col. Edwards: For a time we tried to contact them by radio, but no response. Then they attacked a town. A small town, I’ll admit. But nevertheless a town of people. People who died.

Soldier: I never heard about that, Sir.

Col. Edwards: Well, it was covered up by the higher echelon. Take any fire, any earthquake, any major disaster, then wonder. Flying saucers, Captain, are still a rumour. Officially.
