A month after encountering serious turbulences in an altitude of 100 metres, the tethered balloon has returned to service on the same day. After repairs and a final inspection by local authorities, the balloon had been ready for takeoff for several days. However, operator Air Service Berlin delayed the start due to strong winds.
