Theory is proposed that the "leys, " old straight tracks stretching for miles over
the English countryside, were built by the intelligences behind the flying saucers
for navigational purposes or in order to find readily a form of magnetic current

----- Bavic plotted as a world circle line. Flying saucer review, v. 9, Nov. -
Dec. 19C3: 17-18.
For those who wish to cah::ulate their own orthotenic world lines, author gives
the formula relating !attitude and longitude on a great circle line:
cos ~ =; 1-k 2
""'1--""K-2-co_s_,2,...(""'Q-+-x)....
where ~ is latitude
Q is longitude
and k and x are two constants for the given great circle which may be found
by substituting into the formula the values of Q and ~ for two known points
on the line.
