What,Soviet statistics? The University of East Anglia's statistics proved that we're all gonna burn up in 20 years.
They are not Soviets who counts statistics for air crashes.
Russian civilian airliners are built military way with a lot of structural integrity and most systems dubbed.
For that reason if Tupolev airliner force lands on an abandoned WWII airsrip and ploughs a few hundred yards into thick forrest all passengers are just walking away from that crash. So does an aircraft itself taking off from that same place a week later after some repair.
A lot are still flying in Asia and Africa after 40 years where Boeing will fall apart lacking any proper maintenance.
