I would have replaced the stuffed animals with enough insulation to stuff in that compartment to make the autopilot reasonably quiet. That's no way to live for

I would have replaced the stuffed animals with enough insulation to stuff in that compartment to make the autopilot reasonably quiet. That's no way to live for that long. If it were a regular sound, it'd be miserable but at least you'd get used to it, but it's just randomly heaving and wheezing all the time with no rhythm at all. The worst kind of noise.
