I. Description of Incident
Three airmen observed an object described as being dark and oval-shaped. It appeared to be tumbling end-over-end as it traveled eastward at a low speed. Object appeared to be low. The time of the sighting was 1500Z.
Weather at the time of the sighting was scattered clouds at 2,500' and an overcast at 1,500'. Winds at 1,000' were from 310° at 10 knots and at 5,.000. winds were from 300° at 6 knots.
II. Discussion of Incident
If balloons are launched at 1500Z in Germany as they are in the U.S., this could very well be a balloon. The observers say it was traveling East, which is with the wind.
III. Conclusion
Probably a balloon launched from the air depot.
