This morning photographed a Cargo aircraft (bigger than usual passenger jets) – from a Cricket ground in Mylapore.One could observe a discharge (gas or water) from the wings !
1) Wingtip vortices are associated with induced drag, an unavoidable consequence of three-dimensional lift generation.
2) Aircraft systems prevent ice buildup in one of two ways. On most jet aircraft, hot air from the engines is routed through piping in the wings, tail and engine openings to heat their surfaces and prevent icing.
Not sure of what it is !!!
