I wouldn’t want to fly a Russian plane either.
The IL-62 is a surprisingly reliable if noisy and short-legged aircraft - good enough that a number of Western operators bought them as well as the Japanese (which should tell you something). However, North Korea’s IL-62s haven’t been maintained by Russians or any first/second world country. They’ve been maintained by North Koreans using North Korean resources.
Whether something Russian and complex that was maintained by North Koreans out of local resources is worse than something simple and designed by North Koreans and maintained by North Koreans is, as I said before, something I leave up to you. :D
“I wouldn’t want to fly a Russian plane either.”
A guy that I worked with from a previous job gave a presentation on his work trip in Russia. Lousy living conditions at remote sites. He said the scariest part was the old helicopters.
To extend their range, they had 55 gallon drums strapped to the landing gear. While in flight a guy would open up the drum, open up the gas tank, lean outside and start hand pumping fuel!
