Blake's 7, Series Four

Avon:
[after ordering Slave to plot a new orbit that blocks Belkov's detectors] If we leave our present orbit, as far as he is concerned, we're pulling out - we're cutting our losses and we're running for it. He'll turn his attention to more important matters and leave his automatics to track us. Once we have that moon between us and the scanner, we can start back down again. Since his automatics won't be able to track us, they will merely inform him of what he thinks he already knows - we have gone.

Soolin:
What happens to Tarrant and the others in the meantime?

Avon:
Well, during the manoeuvre they are entirely on their own, but once we are back in our new orbit, the teleport system should function quite normally. Oh, it's a calculated risk. But at least you and I can be certain that we can get away when we want to.
