Some days ago we explained how everyone (including low-tech terrorists "armed" with a mobile device and an internet connection), could have the operational equivalent of a ground-based radar-detection system to predict (and avoid) US airstrikes and reconnaissance missions thanks to ADS-B, Multilateration, online tracking systems, and some poor OPSEC procedures.

However, American and NATO planes are not the only ones that can be tracked on the internet: There is a widespread tendency to leave the transponder turned on while flying close or inside sensitive areas.

For instance, in the last few days, Flightradar24 exposed the Russian military airlift from Sevastopol, in Crimea, and other bases in Russia to Syria.

On September 7, two A124 Condor airlifters could be tracked until landing at Latakia, Syria.
