Here’s an interesting video that was brought to my attention today by a Captain from India.
On Feb 16th 2017, Jet Airways’ flight 9W-118 from Mumbai (India) to London Heathrow failed to make contact with German ATC after being handed over from Bratislava. The aircraft was finally intercepted in German airspace near Cologne at FL360.
The best part about this video is the excellent quality of the footage that was filmed from an other airliner on the same track at a higher level.
