Hello Dimitru, and welcome to the Forum!
Sweet airplane you get to fly there. I've only met one Mig 21 driver so far, but at the time he spoke no english and I spoke no russian. We had a good time in an An-2 simulator however (yes, we were drunk at the time! Hehe).
A good friend of my wife is from Romania, so I am sending her your link so she can translate for us.
Glad to have you aboard!
