2. Mr.
1960, while seated in t the yard of his property and looking skyward, he
observed a dark, ball-ahaped object flying at an extremely high alti-

it flew into a cloud. He kept watch for the object anticipating its
exit from the cloud from the direction from which it had entered and
waa not disappointed when it did so after approximately thirty seconds.
pointed out that since he resides near a USAr installation
and has certain expectations regarding aircraft in flight, he contimued
to observe the object expecting to detect sunlight reflection from its
surface which would normally occur from flying aireraft. However, after
watching the object for a full five mimutes, he observed no reflection
from its surfaces and was surprised to find that the object just dis-
appeared. Although he was unable to estimate its altitude or rate of
