Hi,
Thanks to PJ2 (post #3577) for the drawings and to Machaca for the pictures, especially the second one...

Perhaps my first sights were misleading : looking at the structural line between the two red lines, I can't find anything compatible with rear view of the left wing : on the trailing edge near spoilers 2 and 3, stuctural wing lines aren't parallel to the area line. So, it may be front view of right wing, whose shape could be the one bertween the green lines...
With a bet changing every half day, may be I will find the truth some day: perhaps better to leave this to informed ones!
