How it works:
You choose if you want to see airplanes near you (with location permission) or near a list of big airports.
Flight data comes from adsb.lol's API based on the location chosen.
Your exact location is never sent to the server. I randomize it to a point ~10km away before making any request, since I only need rough proximity to find nearby aircraft, not your precise position.
The only exception is for the "distance to airplane" calculation which is done on the frontend with the exact location.
A photo and details of the plane are displayed like on a digital photo frame. Planespotters.net's API is used for the image library so the resolution is not the best (498x280px). It is better if you use it on a device with a smaller screen, like a phone.
It's a side project. I am an avgeek (in flight school) and saw online videos of similar tools, but without photos and only physical devices with telemetry. So I thought why not make an online version that includes photos.
Feedback is welcomed!
This is the exact reason I added the preset airport locations. You can inspect the source code (dev tools) and see that the location sent is randomized to a point located in a 10km radius, so even in a relatively dense area, no single request can be tied back to your specific address, which was a concern from the beginning.
