The silhouettes of unlit helicopters appeared in the sky over Bolesławiec. Two aircraft circled over the Piastów housing estate and the Zakład Energetyki Cieplnej for several minutes.
These are tactical exercises at the Zakład Energetyki Cieplnej in Bolesławiec aimed at countering hybrid threats. The exercises are intended to test the readiness of the services and improve the coordination of operations in crisis situations. Residents do not need to worry and are asked to remain calm and understanding, as this is not an emergency situation. The exercises will begin on 15 May (Thursday) and continue until 16 May (Friday).
