In two of the airborne and dirty pictures of the Qantas 707 appearing in this months Aeroplane and Flypast, I notice that one of the outboard flaps appears to hang almost vertically and at a different angle to the opposite number which appears to hang normally.
The flap segment in the position in question is on the port side in Aeroplane & stbd in Flypast.
It doesn’t look like an optical illusion to me, though could be wrong, anyone else any thoughts?

If you look at the one on the other side though, it looks a more conventional angle? Perhaps its an optical illusion after all?
I think it is an optical illusion.
The flap mountings are raked at the angle of sweep of the trailling edge and I think that this combined with the large angle of deflection cause the illusion.
And….. common sense would dictate that there’d be a large lift/drag asymmetry if the flaps were set at such a different angle. I can’t see this being a ‘real’ thing.
