wow!
why was this? :3

It was in 20th August, our most important national day, it's like 25th May for you or 4th July in the USA.
We celebrate the foundation of our state with different programs all around the country. In the capital there are many exhibitions, parades in this day. The highlight of this is the firework on the river Danube.

Sadly i haven't took any photo about the dynamic aerial show, the Mi-24V's perfromance was awesome. I never seen a choper to cheat with physics.
But you can watch the whole show here
