That not the significance of this news. The significance is China achieved 7nm using no US equipment or parts. US has the EUV light source technology to make even 2nm, but they don't have the technique so their poster boy Intel can only make 10nm and has to go source 7nm/5nm chips from Asia. China don't got no EUV light source technology, but they already mastered/mastering the 7nm node using home grown equipment! It only matter of time China mass produces 7nm.
Are you referring to the China Eastern Airline disaster? It happened BEFORE the Ukraine War. Your conspiracy theory failed. Better luck next time!
I don't think US doesn't have the technique necessarily but rather it doesn't want to invest in obtaining the technique and find it rather cheaper just to source it from oversea suppliers. Everything in the US is guided by $$. If it's cheaper to source it from somewhere else, even if they are able to produce it in-house, they won't do it.
I'm referring to the China Eastern Airlines Flight 5735 disaster on 21 March 2022 ("Flight MU5735"): https://en.wikipedia.org/wiki/China_Eastern_Airlines_Flight_5735 " China plane crash: All 132 passengers and crew dead, officials confirm Published 27 March 2022 [...] Aircraft manufacturer Boeing - which made the 737-800 jet - said on Saturday its technical team is supporting the US National Transportation Safety Board and China's civil aviation administration with the investigation, Reuters reports. Following the crash, China's President Xi Jinping called for a full-scale investigation. The crash is China's most deadly aviation incident in nearly three decades, and has prompted a national outpouring of grief. [...] " It very much looks like a remote controlled sabotage...
No it was pilot sabotage. Your pilot went cuckoo and decided to drive a plane to the ground killing all 132 innocent lives along with his own pathetic life. That's the truth. The question is does your government have the guts to tell the victims' loved ones and the entire country and admit to the world the truth? Or is going to feed its people some garbage like the weather condition, the mechanical problem or like your wacko theory of remote-controlled sabotage. LOL
