Re: Boeing 737MAX Grounding, General Discussion Thread, Q3 2020

They probably will. Especially if it's just not the FAA that's fine with the aircraft. If Transport Canada and the EASA give the aircraft the okay. they are throwing all that commentary in the bin. The FAA isn't the only putting their a** on the line here. Unfortunately. Apparently the changes will...

The amazing thing for Boeing in the middle of all this is that they still have the NG, which as I recall according to Boeing competes very well with the NEO (and even matches it), so I'm sure they'll be fine once they can get the NG production up to speed again.

Re: Boeing 737MAX Grounded Worldwide Q4 2019

Boeing's annual revenue is over $90 Billion. If you figure a 737 sells for $70 million, eliminating all 737 sales still leaves them with over $50 Billion in revenue. If they shut down the 737 program, it would also eliminate the costs of producing them. So, while it obviously isn't good for Boeing ...
