In the 1970s, Russia was using WWII planes as passenger planes and every rivet rattled and shook or had long been lost. Are they still hiring grandma’s to climb on the wings to eyeball the refueling?
Even in service in foreign air forces like India, Russian military aircraft are prone to catastrophic failures due to less robust design and build quality. After the fall of the Soviet Union, Russia’s civilian airlines upped their fleet quality by buying western models.
