The length of time of the observation, coupled with the winds reported (50k at 50 000 ft) would make the possibility of a balloon se~. UQlikely, since the amount of l ateral travel would be much greater than indicated. Equipment malfunction can reasonably be ruled out since the target was observed for a period of one hour and twenty-one minutes, this also makes propagation anomalies seem un- 2. An extreme temperature inversion is a possible cause of the echoes, such a condition would s how small ~teral travel for the time observed. The rapid height changes reported coul d be accounted for by atmospheric fluct uations. This i s possibl e When it i s con- sidered that t he elevation angle of the antenna is l ow, less than 4, and the ~otal altitude change is only 6ooo ft (a change in eleva- tion angl e of milleradi~) 3.
