  • Am I the only one who

    ...spots planes at 35000 -40000 feet aircraft and photgraphs them? I use the FlightRadar24 Pro app to track cool aircraft (747,787,etc) and then I time it right and go outside with my 42x optical zoom camera and take pictures of them. If you do the same what equipment do you use?
    Also an extra question:
    I have noticed on some clear days that airplanes in transit are, for a fact, not visible. can't even see the tiny shape of the aircraft if for some reason it has no stream.. What's the reason? Also what's the reason where some aircraft in transit don't even have a stream??

    There are a few people who regularly share stunning photographs of planes doing what they do 7 miles high - on the forum page select quick links (at the top of screen) > Todays Posts - of if using Tapatalk select timeline to see the most recent posts.

    Not all planes have full ADSB so cannot be tracked by just a simple receiver. They are tracked using multilateration (MLAT) where several receivers work together to triangulate the position of the plane ... but to do that you need the right concentration of receivers of the right sort in the right area.

      The 2nd paragraph on this link may help. It's all to do with humidity (not to be confused with *relative* humidity)
