Jas-39 Gripen over Hlučín!
A few minutes ago I was curious what makes such a big noise (and who will pay big penalty for flying so low with jet over the city) What a surprise when I’ve seen JAS-39 Gripen training for saturday’s celebrations! Yay, I am excited like a small boy! 
I have been awaiting a surprise but not a supersonic surprise!

According to this information, we will probably need some earplugs tomorrow. Yaaaay!!!! I am supersonically happy
