Boeing's struggles continue: No jetliner sales in September

As nobody is flying, there isn’t the demand.

Boeing could try China though?

All the airlines are suffering pretty badly. End the lockdowns.

Boeing has a very serious quality control problem. Also its foray into space also cancelled due to its failing project. 737Max crashes put Boeing in the headlines as a danger. A flurry of executives left or were canned. This is not what you want to bet your life on, a company with no direction or responsibility.

Downturn is good in that the airlines can get rid of the lemons, which will be their burden of 737Max's. Maybe not all customers will complain, but if they do they will be in the headlines again and again, not a headache an airline needs if it wants to establish reputation in the market

Sorry to say but Boeing problems is due to mismanagement and company EGO!!

Sadly all of Boeing's many problems are entirely of their own making. There have been ongoing labor disputes in their flagship Renton plant and anger over loss of work to their newer plant outside Charleston SC. On top of that Boeing management made a lot of really bad decisions aimed at saving money that instead led to quality defects. Exploding Li batteries in early Dreamliners, a crappy camera system and a major debris problem in the KC-46 program and now the flight control problems in the 737 Max. What else is lurking out there undiscovered?

I wouldn't be surprised if the airlines and Boeing are nationalized.

Not in the US. Bailed out maybe but not nationalized. Boeing is in no danger of bankruptcy having secured private financing after rejecting a government bail out proposal. Long term if things do not turn around in a few years I could see their defense side and Boeing Vertol sold off to other companies and their airliner business reorganized under Chapter 11. At this point that is not necessary.

The bone yard in Mojave is packed full these days. A batch of ex-Quantas 747s recently arrived.
