Don't want to take us too far out into pseudo-science land, but any kind of contact with an alien probe would most likely be intermittent and not reproducible.

Don't want to take us too far out into pseudo-science land, but any kind of contact with an alien probe would most likely be intermittent and not reproducible. For those reasons, even if we observed it in nearby planetary space or in the atmosphere I'm not sure anybody would take the observation seriously. Along those lines, I've always thought the Rendlesham Forest incident[1] sounded the most to me like a story of an autonomous, perhaps self-replicating probe.
