The pictures and videos in this thread are amazing! I didn't realize the SU-30 was such a huge bird.
The PAF should also take part in war exercies with powerful airforces like the RAF or USAF. There is an operation Red Flag in the US every year, there are airforces from allied countries taking part every time. Countries like Israel, Australia, Canada, other European countries. Maybe Pakistan should send it's F-16s and (future) FC-10s for Red Flag.
The ac is very well painted and well managed, If your referring to small shite thing infront of the glass ball, well it is to keep the IRST sensor clean from wind turbulence.
