'I don't know. It just keeps going up.' I wanted to sound scared, and I guess the truth is that it didn't take much effort.
He was talking about the AI. 'No, sir,' I said. 'She just stopped talking. I don't know what happened.'
I could see them coming. Lots of blinking lights a few klicks behind me. The operator kept talking to me, trying to reassure me. I was above the clouds by then, picking up speed as antigrav units tend to do when they get higher and the air gets thinner. It was all I could do not to pour the juice to it, to get out of there before they arrived. But I didn't dare. I couldn't afford to use the extra fuel. I sat tight and eventually the patrol vehicle pulled alongside. There were two officers in it. One waved. Relax. Take it easy. Then her voice came over the radio:
'How do you mean?'
I was thinking if they told me one more time to relax, I would scream. 'It won't come loose. It's stuck.' We continued like that for another minute or so. Then she sighed.
'Good. I'm for-'
'Outside the door?'
'Listen, I'm not going to open anything up here. That's crazy.'
That was good news. 'I'm not opening up. Please find another way.'
Finally, they gave up. We were piling on too much altitude. Kav assured me they'd be back for me, and they pulled away as an airliner passed in the distance. Now all I needed was to get to thirty-one thousand kilometers and get rescued. I was hoping that Sky Traffic Operations was notifying Samuels that a vehicle with a hysterical woman on board was heading up out of control and would need help. I checked the doors and listened for the sound of escaping air. I didn't hear any. The taxi seemed as secure as the AI had promised. I checked the altitude gauge. It was marked up to three klicks, which wasn't much use in determining how high I'd gone. But I could estimate my rate of ascent, so it wasn't hard to calculate. I was maybe halfway to my target altitude when Traffic Control started talking to me again:
'Yes,' I said.
'Okay. Thanks.'
So far, so good. I rode patiently up into black skies. The heating system couldn't keep up, so I wrapped myself in one of the blankets. The galactic haze was rising in the east. And we were burning fuel at a steady rate. When I thought I'd reached more or less the space-station altitude, I burned some more to level off. And I began looking for lights. The messages from groundside went on without a break. Lady in the taxi, it's okay. We're watching you. Samuels has been notified. Help is on the way. Please remain calm. Despite all that, the sky remained empty. My air had been leaking out, and I was beginning to feel it. I reached back for the mask and put it on. The flow of oxygen felt good. I don't think I'd been aware how foul the air had gotten. I began breathing regularly and sat back to await rescue. The ride up from the surface had consumed more fuel than I'd hoped, and I had maybe fifty minutes before the spike would shut down. I couldn't come close to accelerating to orbital speed, so once that happened I'd simply fall back to the ground. Well, as close to the ground as I would get before burning up. It was time to take matters into my own hands. I got on the radio. 'Samuels Ops,' I said, 'this is Janey Armitage.' I made up the name. 'I'm in a runaway taxi. Something went wrong with the spike, and it's taken me God knows where. Please help. I'll leave the transmit on so you can track me. Please hurry.' I looked out at the empty skies. 'The fuel gauge is near empty, and I don't know what will happen after that.' They would know, of course. And they answered immediately:
'Don't know,' I said. 'But I'll be glad to get out of here.'
Chilling words, those. The guy wasn't even close to me yet. 'What's the problem?' I said.
I'd debated picking up a pressure suit in case we had to do a space walk, but I hadn't been able to see any way to explain its presence to the rescuers. Hiding the oxygen tank would be tough enough. If they figured out that I'd engineered the whole thing, they'd waste no time turning me over to the authorities. So I'd had to take my chances. 'How long before it gets here?'
'That's not going to work.'
'Air's okay, but fuel looks like about forty-five minutes.'
'No.' I held back on the wisecrack.
While they were figuring, a cluster of lights came out of the night behind me. The lights were higher than I was, and off to port. While I watched they grew brighter and blurred past. 'That Samuels?' I asked.
