Ok guys! The crew rest was U/S the other day so i went to sit down in C Zone (B744). I was sitting on the right hand side watching a movie ("The Hot Chick"....dont bother!), when i decided to open the shade and take a look outside. As we were in light chop, the wing was bending and I could see the refraction (appearance as i described in my post above as "hot jet of air" like apperance) moving inboard then outboard with the bending of the wing.
I had not had any bottles of wine...
Hope you all get to see it... truly amazing.
