Scobie,
Yes, I also tend to over-estimate the plane's distance away from me. The
shadow cast by the plane can sometimes be useful in this regard as an
indication of exactly where the plane is in relation to the ground (of
course the relative positions of sun, plane, and ground have to be
considered).
If Chuck Anderson is correct that larger planes cause the opposite
perceptual error, there should be a particular plane size in-between whose
distance away we can accurately guess!
