Warning! This is a brief intro into chemtrails with examples of various operation with instructions in Croatian. Chemtrails, grid-patterns, cloud formation, cloud destruction – most photos over the town of Pula – population 50 000. Thank you very much and have a nice day – if possible! UPDATE: A clip in English, Italian and Croatian concerning visual proof and pertinent questions that was on the channel was banned by Youtube administrators without offering even the audio-swap option.
