The vector angle from P1 to P2 is
d = sqrt[(x1-x2)2+ (y1-y2)2].
The coordinates of the point dividing the line segment P1P2 in the ratio r/s are:
([r x2+s x1]/[r+s], [r y2+s y1]/[r+s]).
As a special case, when r = s, the midpoint of the line segment has coordinates
([x2+x1]/2,[y2+y1]/2).
Isn't that just the long winded way of saying that the shadows are only different because the nose of the aircraft is so much nearer the sun, thus in fact taking advantage of one of the square laws of nature in so much as opposite shadows attract due to, in no small measure, the light refracted by the air sinking above the cooler shaded tarmac under the fuse interacting with the rising air above the tarmac in the open (which causes both tortional and lateral buckling of the reflected light), inducing a refraction into the negative co-efficient of the cast shadow?
Simple really....
Tige. Deadset priceless.
