全國全面的品管工程之落實，中國，日本之間，百年的差距：
看了日本片，檢討中國總體個體各產業農工等，水資源的管理與效率，都是約日本的水道局等的十分之一……從日本的標準，中國是極落後，浪費，無效率的國度。

【數據不可靠】參議院重量級共和黨人抨擊勞工統計局 質疑經濟數據可信度
https://reurl.cc/aZln6G
兩位重量級共和黨參議員Bill Cassidy（圖右）和Susan Collins（圖左）抨擊了負責發佈月度就業報告的美國政府統計機構，稱最近對初始數據的大幅修正表明其在編制關鍵經濟數據方面「持續失敗」。他們表示，該機構無法提供初步可靠的數據是「不可接受的」。這兩位議員明年將擔任監督勞工統計局的重要角色。

A Boeing supplier notified the company that it had discovered "non-conformance" with the way some holes were drilled in about 50 undelivered 737 jets, the company said.
Some fuselage holes on those planes "may not have been drilled exactly to our requirements," the Boeing Commercial Airplanes CEO said.
"While this potential condition is not an immediate flight safety issue and all 737s can continue operating safely, we currently believe we will have to perform rework on about 50 undelivered airplanes," he said.

2018年和2019年，在不到五個月的時間裡，波音737 Max 8飛機發生了兩起墜機事故，共造成346人死亡。後來發現兩起墜機事故都與一個會無視飛行員指令的系統故障有關。
這些墜機事件導致波音737 Max飛機在全球範圍內停飛，數百架飛機在世界各地的停機坪上停放了近兩年，工程師們努力查明並解決問題，以便監管機構重新認證這些飛機。

機身在半空中破裂，在飛機側面留下了一個門大小的洞，這架噴氣式客機隨即返回波特蘭機場。
事故發生後數小時內，阿拉斯加航空表示，將停飛機隊中所有65架波音737 Max 9飛機，直到機械師能夠仔細檢查每架飛機。週六晚些時候，聯邦航空局下令其他一些航空公司暫時停飛該機。
在阿拉斯加航空的事件中，飛機是在美國製造的，在美國飛行時失去了一個機身部分。因此，美國國家運輸安全委員會將是負責調查該事件的牽頭機構。
安全調查可能需要數月時間，涉及來自政府、運營飛機的航空公司、工會和飛機製造商（具體這一次是波音公司）的技術專家。
空管局不需要等待安全委員會的報告，就可以決定是否停飛某一型號的飛機，或者下令立即進行檢查。無論如何，航空公司一旦知道要檢查什麼，通常都會立即檢查飛機。
