This was a great story, a wonderful tale of humanity shining through despair and hopelessness. I was taken in completely by the narration and quite affected by the ending.
Later, though, I had a few nitpicky thoughts - the primary one being "why was the wheelchaired guy even there?" I mean, the aliens had a planet of several billion to choose their few dozen slaves from. Why choose a guy sitting on a piece of technology they do not understand? It couldn't be because he would be less of a threat because: A - it was clear no-one was a real threat to them, and B - because the other slaves were not disabled. If the aliens were killing people left and right except a few they choose as slaves, the wheelchair guy seems like a very odd choice for them. The second nitpick was already brought up above - it was very, very lucky for the bottle of wine + the gasoline to end up in the same shipment. And besides, it seemed like the distraction plan relied on some sort of ignitable fuel becoming available, but the narrator had said it almost never does, and when it does it could be a trap. There was something of a McGuiverness to the whole thing - he happened to have pre-prepared the exact things he needed to take the maximum advantage of the situation exactly as it happened, even though he had no way to forsee it.
Still, the fact that these thoughts hit me several hours after listening to the story (and indeed, the fact that I was thinking about it several hours after listening), rather than during the story, is a testament to how well crafted it is.
