the plane flew for 7 hours after hitting 45,000 feet
so and just askin...it is verified the plane was at 45 k feet ?
It is unlikely it ever got that high.
Yeah, I know, 'radar' and all that. Well, primary height-finding radar is not all that accurate, and FL450 is above the 777-200 capability, well above certified.
I heard a pilot with 30 years experience and well qualified to fly a 777 say that plane could have made that “6 to 7 hour flight”, including all the turns and changes in altitude, by itself with the pilots incapacitated.
