«The very scarcity of inforastion available reveals the eeed for ob-
servations at high altitudes, particularly in equatorial regions, to be used
in basic research and in the design and operation of sanned and unmanned
wehicles at chese heights.

The requirement for wind inforsation at Orange-shot altitudes aod
above is obvious,
To estimate the effect of wiod errors on cloud sovement, and thus the
wind influence on successful penetration, computations of the probability of
hitting a solid circular cloud were =ad2.
le was assumed that the cloud
would aove with the speed of the wind, that a large torus would pot fora
Tapidly after the burst with below-miniam density of debris in the center,
and that vector errors in hitting the cloud would be randanly distributed
and could be represented by a normal bivariate distribution, where the sup
of errors in each orthogonal direction are equal, i.e., a circular distribution.
In polar coordinates 9 and -, with standard deviation 3 of these
errors, the probability of penetration is:
