"Dutch Roll is a coupled out of phase movement of the aircraft as result of weakened directional stability (provided by the vertical tail and rudder), in which the aircraft oscillates around its vertical as well as longitudinal axis (coupled yaw and roll)." That sounds pretty scary. I wonder why it wasn't bigger news when it happened last month?
Earlier quoted context omitted.
No fan of Boeing. But where are you going to go to buy something else? There is only Airbus. There isn't a huge competitive market, it is just 2 companies left standing. Perhaps a good argument for fighting monopolies? And, while Boeing looks bad, when sales go down, corporations adapt. The pesky customers want "Safety", and we aren't selling "Safety", got to get some of this "Safety". Guess we better do some re-orgs…
>The pesky customers want "Safety", and we aren't selling "Safety", got to get some of this "Safety". Guess we better do some re-orgs, some focus groups, some training to make sure everyone knows "Safety" is important. Maybe throw in some training on "Quality". Gah hahahaha. Oh God, don't make me laugh that hard. One does not merely add some more Quality to a product as if it were flour in a cooking recipe. Quality i…

Not as scary as flying upside down which is what I originally thought based on title alone. Most people are familiar with "barrel roll" but by comparison this just looks like wiggling. Counterintuitively though my understanding is that barrel rolls are generally safe even for large planes since it's a stable 1G maneuver (some jock irresponsible air force pilot used to regularly barrel roll B-52s until he did one too…
Maybe "safe" here means that merely the stress of the maneuver itself wouldn't destroy the craft? But surely the loss of lift is likely to put it at significant risk, as in your example.

> why [Dutch Roll] wasn't bigger news I think the name is a serious problem. Something like “uncontrolled aircraft orientation” is more descriptive. “Dutch Roll” brings to mind thoughts of “is it better than Swiss Cake Roll?” and “is this news-spam for Hostess brand emerging from bankruptcy?”
This is an aircraft worth taking great lengths to avoid. Cancelling important trips, meetings, etc.
As a Dutchman the endless list of apparent “Dutch” things never ceases to surprise me. Uncles, courage, ovens, double, going, etc., and a new one to my list: rolls. And none of them means any good.
