Here is Carlos back in May 2014. Perhaps someone can translate? Is he claiming to be an ATCO in the video?
He obviously has history with the state sponsored Russia Today so perhaps his social media was an easy target for the Russian Internet Troll Army?
The following is a google translation of the video description. Is Carlos playing them along as to his job description or is it a case of a misinterpretation?
Express what one thinks about the crisis in Ukraine can even lead to an alien to be forced to flee for their lives Kiev. It is the case of a Spanish air traffic controller who was threatened by supporters of the Maidan.
Carlos, who spoke with RT on the condition of anonymity, has received threats despite not defending any interest. "I have my opinion and my view of a normal person, with a separate work [unrelated] or media, or any political party, nor to any association."
