We can see anything that flies IFR pretty accurately. We get lots of ghost "unknown" signals all the time. You go crazy trying to figure out what they all are. This is after military is filtered out too, so you just wonder... ;-)

When a plane strays from its flight path, nothing happens. It happens all the time. Unlike a highway, you have no roads with markers that let you know you're off... many pilots aren't perfect anyway. Lots of them are pretty precise though.

We're not responsible for national security. Even if we did see something out of the ordinary, we can only report it. But I'll tell you what, if I see a vonvoy of UFOs over your house I'll let you know.
