Only the management suckup with the lanyards and 777X shirt and the Boeing PR escort behind him look happy. The rest are glum, wondering how many seconds are left till they can go home, away from their jobs at the most corrupt large company on the planet. 

The start of production on any future defect riddled, almost built when delivered Boeing airplane isn't a significant date at all. The date people really want to know is the date there is no way to know--the day that defective airplane will crash so they can make sure they are not on it that day. 

As no one can know the date that any one of thousands of defects on a Boeing plane will cause their plane to crash, the only rational and safe thing to do is to never fly on any Boeing plane, and fly Airbus instead.

If enough people protect themselves from the Boeing Board room directed QA fraud behind those defects, the unhappy workers pictured above will get their dearest wish--a job elsewhere.
