Aerion, who is competing with BOOM supersonic, got a huge boost when Boeing invested and partnered with them in Feb 2019 but once again, Boeing's word is shown to mean nothing as they walk away from thier "partner". Sound familiar? Yep. Embraer can console Aerion over a beer sometime.
For those of you who were told "you are safe from layoffs" or believe there are only 2 more rounds, or that the next one won't be as big as the last. Remember what Boeing's word is worth. Take a look at the carnage left behind of all those who have believed Boeing in the past.
Good luck to all of us.
