With the coronavirus this is a huge 1-2 blow to Boeing.
I wonder how much of their go forward business will be military contracts, as the their civilian aviation business seems to be dead for the next 3-5 years.
They can get the 737 Max recertified to fly, but I think the damage to the reputation is done, so they probably will need to release a brand new plane to be competitive. Not sure on the design to production timeline for an airplane, but that's where I assumed 3-5 years.
