reported (50k at 50,o00 ft) would make the possibility of a balloon
seem unlikely, since the amount of lateral travel would be much
greater than indicated. Equipment malfunction can reasonably be
ruled out since the target was observed a period one hour and
twenty-one minutes, propogati seem un-
likely.
2. An extreme temperature inversion is a possible cause of the
echoes, such a condition would show small la teral travel for the
time e observed. The rapid height changes reported could be accounted
for by atmospheric fluctuations. ror oy acaosplerzc 1 This is possible when it is con-
sidered sidered that the elevation that the elevation angle of the antenna is low, less than less than
