That's a question with a lot of qualifiers. On any given workday, there are several military and commercial jets overhead, plus a variety of dickheads doing loop-de-loops in a prop plane. Sometimes, if they get close to the house, I'll take a look. I might see them, or not. We have the Portsmouth airspace nearby.
If I take a walk, I may see one, but usually not. If I'm not working, I'll probably see at least a few during my day. With the Flightradar24 app, I can see all the international flights passing over at 40,000 feet.
