My radar picked him up when he was about five hundred miles to my north-northeast and about forty-five miles above me. I switched the velocity calculator on him as fast as I could reach it.
The enemy ship was doing sixteen, possibly even sixteen and a half. I took the chance that it was most likely an Ivar Interceptor, at that speed, and punched out a temporary evasion pattern with my right hand while with my left I snapped an Ivar K-12 card into my calculator along with his estimated speed, altitude and distance. It wasn’t much to go on as yet but he couldn’t have much more on me, if as much; inwardly I congratulated myself on the quick identification I’d managed.
He was near enough now for my visor screen to pick him up. At least he was alone, that was something. My nearest squadron mate was a good minute and a half away. It might as well have been a century.
Now, this is what is always hard to get over to a civilian; the time element. Understand, it will take me a while to tell this but it all took less than sixty seconds to happen.
He had guessed my evasion pattern already--either guessed it or had some new calculator that was far and beyond anything our techs were turning out. I could tell he’d anticipated me by the Bong-Sonic roll he slipped into.
I quickly punched up a new pattern based on the little material I had in the calculator. At least I’d caught the roll. I punched that up, hurriedly, slipped it into the IBM, guessed that his next probability was a pass, took a chance on that and punched it in.
I was wrong there. He didn’t take his opportunity for a front-on pass. He was either newly out of their academy or insultingly confident. My lips felt tight as I canceled the frontal pass card, punched up two more to take its place.
The base supervisor cut in on the phone. “It looks like old Dmitri himself, Jerry, and he’s flying one of the new K-12a models. Go get him, boy!”
I felt like snapping back. He knew better than to break in on me at a time like this. I opened my mouth, then shut it again. Did he say K-12a? Did he say K-12a?
I squinted at the visor screen. The high tail, the canopy, the oddly shaped wing tanks.
I’d gone off on the identification!
I slapped another evasion pattern into the controls, a standard set, I had no time to punch up an improvisation. But he was on me like a wasp. I rejected it, threw in another set. Reject. Another!
Even as I worked, I kicked the release on my own calculator, dumped it all, selected like a flash an Ivar K-12a card, and what other estimations I could make while my mind was busy with the full-time job of evasion.
