The problem with your approach is that the page first loads a view, then performs regular requests to refresh the page. If you look at the network tab in the developer console in Chrome (for example), you'll see the requests to https://data-live.flightradar24.com/zones/fcgi/feed.js?bounds=59.09,52.64,-58.77,-47.71&faa=1&mlat=1&flarm=1&adsb=1&gnd=1&air=1&vehicles=1&estimated=1&maxage=7200&gliders=1&stats=1

The response is regular json:

{
  "full_count": 11879,
  "version": 4,
  "afefdca": [
    "A86AB5",
    56.4288,
    -56.0721,
    233,
    38000,
    420,
    "0000",
    "T-F5M",
    "B763",
    "N641UA",
    1473852497,
    "LHR",
    "ORD",
    "UA929",

  ],
  ...

    0,
    "AAL291",
    0
  ],
  "stats": {
    "total": {
      "ads-b": 8521,
      "mlat": 2045,
      "faa": 598,
      "flarm": 152,
      "estimated": 464
    },
    "visible": {
      "ads-b": 0,
      "mlat": 0,
      "faa": 6,
      "flarm": 0,
      "estimated": 3
    }
  }
}

I'm not sure if this API is protected in any way, but it seems like I can access it without any issues using curl.

More info:

• aviation.stackexchange - Is there an API to get real-time FAA flight data?
• Flightradar24 Forum - API access (meaning your use case is probably discouraged)
