2. Imagine the sheer pain of duplicating every single process and spec to the minutest detail, nobody is flying an airplane that only 'works' 99.99% of the time. Probably easier to start from scratch and learn it. BTW, this was tried by Russia in the all through the '80s, they tried to steal all advanced tech. but by the time they duplicated the stolen technology, the next generation appeared. A losing battle.
Not the ones that were forked due to abandonment, but the forks due to “irreconcilable differences”.
Might I introduce you to the Tupolev Tu-134?

Also perhaps the 737-MAX. :)

Some searching says...
1. >1000 flights per day for the family
2. 2 US carriers accounting for more than 200 Max 8 per day
So one would have to get to 20,000 flights after two crashes to get 2 nines. We're well past that threshold
Said differently, the Max 8 was working safely 99.999% of the time, while the 737 NG was working safely 99.99999% of the time. An order of magnitude better than 99.99%, but two orders of magnitude worse than expected...
It is certainly a lot safer now. Hopefully even better than the 737 NG.
Air safety seems the quintessential "discounting the horror of extremely rare accidents from the actual total safety rate" mental trap.
When it's years between incidents, and that widely used? Yeah, I'd still fly on one if I needed to.
But I swim in the pool during thunderstorms too, so not really a zero risk type person.

though that one was so defective that even the Soviets didn't want to risk flying it. it could barely get into the air, and that'd be with several major faults and alarms blaring.
> Capable of operating from unpaved and gravel airfields with only basic facilities, it was widely used in the extreme Arctic conditions of Russia's northern/eastern regions, where other airliners were unable to operate.
The 737 Max 8.
2. Aviation in the USSR was developing completely independent, and you can accuse USSR in stealing technology in many areas but certainly not in aviation.
