Re: Boeing 737MAX Grounded Worldwide Q3 2019

Except it wasn't 40 seconds. The pilot in Command properly counteracted MCAS about 17 times over 9 minutes during which he had control before handing it over to the co-pilot who failed to properly counteract MCAS down. He handed over control to try and find the problem in the manuals - but unfortun...

Re: Rumor: Airbus to launch A350-1000ULR

True but they are basically even now with the 777-9 having more modern engine tech. Once the engines are at parity the 777-9 will only have capacity as an advantage. We see how well that worked out for the A380 vs the 777W. Well capacity does seem to be an advantage for Cathay and British Airways, ...
