Why doesn't anyone take binoculars on board an airplane to observe while traveling?
Good evening. Why doesn't anyone take binoculars on board to observe the landscape at cruising altitude and at low altitudes when there are few clouds? If, as a passenger, you look diagonally downwards out of the airplane window at a 45° angle with binoculars (zoom binoculars with a maximum magnification of 30x), you can see everything much more closely. For example, on a flight from Düsseldorf to Warsaw you can see the Ruhr region, Münsterland, the Hanover area, the Berlin area, western Poland, etc. From an altitude of 11 km with 20x magnification = 550 meters field of view. That's enough to make out individual buildings.

I've already done that. Have you ever looked through binoculars at 20x? They wobble like a lamb's tail! Unless they're stabilized, like my 18×50 Canon binoculars. Leitz has a 20×50, but it's unaffordable, around 6-8k. So much for your example…
However, if you hold your binoculars lightly against the window in an airplane, they will stabilize themselves. You don't need to see everything perfectly. My main concern is that you can at least roughly make out individual buildings from the plane. And this works very well.
You're welcome to do that if you're interested. I almost always have a window seat on flights and enjoy looking out, but I don't really have the urge to examine the landscape below in detail.
Because no one has come up with this brilliant idea yet
