Re: Boeing 737MAX Grounded Worldwide Q3 2019

Anyone has an idea how many planes parked out of the shop? I wonder if Boeing will have to cut production rates down again soon, must be hell of a strain on the cash flow to have all these parts and planes sitting around. production keeps running at 40 frames per month, down from 50.

Nope. Boeing definitely won't go under before there is a competitive commercial (aircraft) airframer in a low-cost country.

If ramp kept pace with trends, your likely looking around 6/month by end of this year, or in around 18 in last quarter.
