&t approximately 2240 hours, on 21 July 1952, { was roturning
from checking the Base iursery. I was driving south at a speed of
a tely 10 miles per hour, Suddenly a solid white circle of
light appeared in frort of me, pimilar in shape end color of a full
moon but far more brilliant like looking at a white hot iron through
@ scwall hole. The object was not too high above the horizon, maybe
1000 feet. It rose at an extremely high rate of speed at an angle
of 60-75 degrees at maybe 15,000, 20,000 feet it leveled off smoothly
like an aircraft under good control would level off after a very
rapid climb, The light went off suddenly like it was shut off or
went in a cloud bank, though no clouds were visible. The contour
wes snooth (oxtremely or perfectly co). No jagged edges or tails,
smoke, or other colors wore noticeable. I was Dase 0. D, at the
tine.

On 21 duly 1952, at approximately 2240 hours, the wife and I vere
returning from Lockhart to San Marcos and at Maxwell, Toxas, we noticed
an object. It looked like something had exploded and it gave off a rod
flame and started to descend with a following blue flame which was very
bright and appeared like a flare. It descended to about a ostimate of
5000 feet. It stopped and apreared white in color and I could identify
the object as being round. ‘he color seemed to change to very light
yellow and the object moved off to the ecuth. It was quite fast.
