If the 737 was de-pressurizing at 30+ thousand feet AGL they HAD TO GET DOWN to around 8,000 feet to avoid losing people. I can see spiraling as opposed to just diving to avoid a hard pull-out. If the crew had a suspicion as to why the de-pressurize that might have affected/proscribed the pattern to get down.
Since it’s Boingboing one has to be suspicious that they might have lost another important part, like, oh, say, a window or door? There was just another incident where a Boing developed a windshield crack at 40K, didn’t lose pressure but had to get down for safety.
Re: Boeing 737’s—
Are most of these incidents with the 737’s?
Flying in August and want to be aware …
