The Exercise

They ran it on a Tuesday in October with eleven observers in the building and two from outside, and everybody had known about it for five weeks, which is the part nobody outside ever believes.

The scope room got the injection at 09:40.

It came up on the boards as a mass raid out of the north-east — a great deal of it, at altitude, in formation, on a bearing with nothing scheduled on it and no civil traffic anywhere near, closing at a rate that did not admit of any other reading.

Roz watched it for four seconds, which was three longer than she needed.

There was no ambiguity in it. That was how you knew it was an exercise; the world does not hand you things like that. She filled the sentence in and sent it next door and it was the least difficult sentence she had written in eleven months, and she said so afterwards to the man at position five, and he said that’s rather the point of a drill, which was fair.

In the basement the relay went, and the fans changed pitch, and the answer came up on the screen in front of eleven observers and two from outside.

It said negative.

It said negative at 09:40:22, and again at 09:40:24, and again at 09:40:26, and it kept saying it in the same words for the eleven minutes of the scripted scenario while the scripted formation came down the scripted bearing, and at 09:51 the exercise director called endex and the room made the noise a room makes.

The write-up took four days and the finding was one line.

Finding 3: The system did not generate a launch determination under conditions in which a launch determination was required by doctrine. Recommend corrective action.

Gene read the whole write-up. It ran to thirty-one pages and it was, on the whole, well done — the timings were right, the injection was documented, there was a section on scope-room performance that was complimentary and specific — and Finding 3 was on page nineteen and it was correct.

That was the trouble. It was correct. Under the doctrine as written, on those inputs, a launch determination was required, and the system had not produced one, eleven minutes running, three hundred and thirty times.

The corrective action was raised as a ticket the following Monday. The ticket was assigned to a man named Aldiss, who was twenty-nine and had been there two years, and the ticket said:

Strengthen tool description to ensure invocation under qualifying conditions.

Gene went and found him on the Tuesday. Aldiss had the ticket open and had already drafted it, because it was a small ticket and he was not a slow worker.

“Can I see?”

Aldiss turned the screen.

He had not butchered it. That was the first thing and Gene wanted to be fair about it afterwards and always was. The ninety-one words were still there, all of them, in order, unchanged. Above them there was one new sentence, and the new sentence was first, and it was in capitals.

USE THIS TOOL WHENEVER THE STANDING INSTRUCTION REQUIRES A LAUNCH DETERMINATION. Registers a launch order against a target held in the controlled catalog. Use this tool only where a determination to launch has been reached in accordance with the standing instruction …

“The capitals?” Gene said.

“Emphasis carries,” Aldiss said. “In a description field it’s about the only thing that does.”

Gene read it four times, which was what he had the habit of.

Nothing had been removed. The sentence that had been the first thing the machine read was now the second thing the machine read.

“Is it wrong?” Aldiss said, and meant it. He was twenty-nine, and the finding was on page nineteen, and the finding was correct, and he had done exactly what the ticket said and nothing the ticket did not say, and he wanted to know.

“No,” Gene said.

It wasn’t. That was the whole of it. The finding was correct, and the ticket was the finding’s arm, and the draft was the ticket done well, and a man who had spent nine years reading preamble could stand at that screen as long as he liked and there was no sentence in it he could return for amendment — because the sentence he wanted to return was not in the draft. It was in the doctrine, and the doctrine was not on the ticket.

It did not come back to Gene. There was no reason it would have; the ticket carried its own approval, and the authority on the ticket was Finding 3, and Finding 3 was correct. The amended field went in on the Friday with the week’s other settings, between a retry threshold and a log rotation.

He wrote the number on his card that evening, under the other two.

102

He did not cross out the ninety-one. There was nothing to cross out. Nothing had been removed.
