Last Year when I was taking a flight back from Kolkata to Guwahati,I managed to get something on my cell that I never expected.At that time I was using Nokia Lumia 720 and as you all know after boarding the flight the cell should be on flight mode,even I did so..But the GPS of my cell was working with an app HERE DRIVE,So I started the app and this is what I got….
