At aprroximetely 2120 Central time, a light, wita a briliisance siigntly
sreater thon a star apneared from the West traveling in an easterly

direction at a high rate of speed. ft first svuveared slightly above the horizc
of a clear moonlight night. There wes no audible sound. IS appeared to

be at great height altho it was impossible to determine the altitude,

It traveled a sigezag course with frequent bursts of speed similar to a

water bug soft spurts and stoos scross the surface of water. Directly overhesd
it changed course 90° into the South, Arter 5 mimtes it turned southwest

end was lost in the brilliancy of the moon, At 2145 Central it was not

longer possible to observe it.

A coll was placed to Maxwell 71d operations concerning the phenomena and
inquiry was made if any experimental sircraft were scheduled for a flight
in the vicinity Dut the renly wes negative. Wo nlamsible exolanation was
otfcred for the umsual -ction of this source of Light woich acted contrary
to any common aerodynamical laws. ‘Two of the 2bove noted ovservers wers
rated vilots and the other two, air intelligences officers.
