I was supposed to be there for 1 day in order to get more acquainted with EATA. During the day I met with Krista and Hedi. At one point I realised that having a captivating conversation about NATO, the association, present, past and the future that 6 hours had passed in a blink of an eye. With the everlasting conversation I presented a few ideas that could be realised within the NATO’s 70th anniversary. Krista invited me to meet with the organising team and then as they say – the rest was history.”
