    Planefinder.net is very useful in that it has archives going back several years. I recently wrote a converter that lets you extract the track of a plane and view it in Google Earth with the correct timestamps and altitudes - similar to FlightAware's downloads.

    To do this you need to extract the "payload" for the track. This is what PF sends to your web browser when it displays the track in the map. It requires a little trickery.

    In Google Chrome, you will need to open the Developer Tools

    Select "Network" and "XHR", type "position" in the search box
    20170108-145146-k15kj.


    Then click on the plane you want, then look in the debugger for the planeposition packet (you might want to clear it first, to make sure you get the right one.

    Then Right Click on it. and "Copy -> Copy Response"

    That will give you something like:
    Code:

    And paste it into the top box

    The bottom box will give you a preview of the KML file. You can just ignore this.

    Click on "Download KML", and open in Google Earth

    Current problems are that it does not interpolate well where ADS-B coverage is weak, so goes below the surface of the Earth.

    It looks like Planefinder has changed the details of how flight paths are requested and returned, and are now encrypting/obfuscating the flight path response.

    When I click on an aircraft, it makes a request to


    For example:


    The response comes back as binary. Here's a hexdump of an example response:

    You can see it unencrypted if you put a breakpoint in the updateFlightPath function
    Metabunk 2019-04-26 13-01-44.

    Add a watch to JSON.stringify(s) to get it in JSON, which you can then use as above ( I just tried it, it works).

    Of course that only works if you click on the plane, but their data isn't mean to be a free-for-all.
