I wish more airports embraced planespotting! I enjoy planespotting at SFO regularly- I go to Bayfront park and get decent views of traffic departing/arriving the 28s (longest runways).
Additionally, the Autobahn is next to the airport, and planespotters also occupy the dirt just beside that.
And since the main approach is from the east, you have kilometers of fields with small dirt paths in that direction where you can watch airplanes very low and directly overhead.
When I lived in previous houses: the Goodyear blimp, the Space Shuttle (up and down)
I bet you never get the Space Shuttle in Frankfurt.
The Goodyear blimp was a weird buzzing noise, not that loud.
The Space Shuttle launch was at some distance, otherwise the brutally loud noise would have killed me by ripping my internal organs loose. I had about 30 miles of safety margin, giving a house-shaking rumble. Landings were quiet except for a BOOM BOOM as the shockwave passed over. That would rattle the windows.
The An-225's six engines got me running to the window, though more for the oddity of the sound. At the time, that was the world's largest operational aircraft.
The V-22 is another one that sounds really weird, but it isn't actually loud.
All the fighter jets are loud. We get lots of them for about 3 days per year, during an airshow. Four or even six of the Blue Angels or the Thunderbirds making a turn around my house is quite noisy. Otherwise, the rare fighter jet flies through maybe once or twice a year.
The most awful noise was actually not on my list, because it isn't interesting. Delta likes to fly a decently large jet (probably 737-NG, 717, MD-80, or MD-90) at around 6:55 AM.
So jealous. I'd love to see one of these things in the metal, let alone see / hear it taking off and landing.
I saw the An-225 departing. I heard it, felt that the sound wasn't typical, and ran to the window. I spotted the six engines and the distinctive H-tail just in time. That was a jolt. I see that and, well, there can be only one plane. It's that one, unique in the world.
It turns out that my local airport (MLB) sometimes does maintenance for the An-225. I'm not sure why this would be done in the USA at all, but we do have a 10,000-foot runway and huge hangars that I suspect were built for the Convair B-36 Peacemaker. The An-225 has probably been here more times than I know. Maybe I could see it often if there were some way to get notified in advance. Maybe there is even a predictable schedule.

I don't think it is all that much compared to the Boeing VC-25 (with Trump) or Antonov An-225 Mriya, both of which landed at the airport.
Anyway, until recently the last airworthy Vulcan bomber would fly very low over our house when these shows were taking place. Ridiculously loud thing and absolutely awe-inspiring. Sadly it's not flying anymore due to lack of spares and too many accumulated hours on the airframe.
It doesn't have a great view other then that really, but I think that's a pretty cool unique view.
