However, i somehow cannot get it to work. exporting works fine for current flights (just open View->list, then click on the .kml button to export. However, when i am in a playback timeline and change to view->list, i jump from timeline to current flights and loose the flight that i have been 'tracking' (by clicking on the plane). So, how can i export the .kml for a historic flight? BR Dave What makes the planes do this on Flight Radar 24? FlightRadar24, unlike most other tracking websites, attempts to display a literally real-time indication of an aircraft's location. I am having the same issue with the 3 browsers I have tried with windows 10 today. I am trying to see what aircraft i am uploading using the map, radar view, local traffic option but i just get the complaint from www.flightradar24.com "could not load local data:error" flightradar24.com says i am uploading from that local ip address Below cruising altitude, line-of-sight weapons would make Flight Radar redundant to common binoculars and scopes. Terrorists aboard an aircraft would make Flight Radar a non-issue. Not to mention, the terrorists would probably try to turn off the transponder and ADS-b. A similar argument was made for the use of GPS when it was first created. A few days ago the website version of FR24 started lagging when I click on an airplane. It doesn't show the flight info or path for up to a minute while it appears to load the info. Is this a known issue or something just local to my laptop. Several key things define whether an aircraft shows on Flight Radar and any other tracking site: These sites do filter some aircraft and choose not to display them. A plane may choose to turn off their transponder. Military aircraft in particular are exempt from many civil rules and regulations which would see most aircraft having an active transponder and of course their operational ... IMPORTANT NOTICE! Before you post on Flightradar24 forum you must read this important information about Flightradar24 But yet, FlightRadar24 shows a flight a few weeks ago, perfectly tracing the coast north of San Diego, 2,000 miles from my home airport in Kentucky. How is it possible for ADS-B tracks to show up under the wrong N number? It is not one blip of data with a bad ID…it’s hundreds of data points over 50 minutes with no discernible glitches at all. I am pretty certain that years ago, it was possible to display only a particular airline's active flights on the radar map. Try as I have, I cannot remember how to do it and a search has not revealed the answer. Flight radar 24 shows GA traffic in some occasions, but in general it cannot track these aircraft. FR24 works primarily on ADS-B, which is a surveillance technology that transmits aircraft information including position.
