Fully agree. Creating a good summary from one source is something that already requires me to concentrate and it only gets more difficult when multiple sources are involved. Writing verbose stuff is easy, but concise text takes time. Blaise Pascal knew,
"I have made this letter longer than usual, only because I have not had the time to make it shorter."
PS. I'm not going to say how long it took me to write this post
If you'd like to see more examples of the above I'd recommend you take a look at The Tyranny of Metrics by Jerry Muller. El Reg readers will be familiar with many of the types of mad metrics he analyses and there are some examples showing how to do it properly too. I'm currently working in project management and leave my copy on the desk to annoy my EVM obsessed boss.
Call me naive but how can data science work in cases like this if there isn't a meaningful dialogue between the people with the domain knowledge and the data scientists? We have a huge amount of operational data where I work and to make better use of it people are teamed up with data scientists or they are offered some basic data science / analysis training. There is a great deal of benefit to be had from this data that doesn't require the full blown 'scienetific' approach.
The regulations require the nacelle to contain a broken fan blade, but assume that failed bits at the turbine end of the engine will escape obliging the designers to maximise systems segregation in the zones of the aircraft that could be impacted. This meant that despite the fact that the Quantas engine failed in a spectacular manner there was still enough systems redundancy to allow them to get back down.
I'm based in Europe and the company working language is English although most of the employees aren't. Here they use FFS to mean First Flight Standard which always made me smile. After explaining the alternative meaning to my French boss he now takes great pleasure in using it inappropriately in meetings to try and get me to laugh. We also have a First Certification Standard so as not to forget those with religious sensibilities.
The MCAS was introduced on the Max because the installation of the new engines changed the center of gravity leaving the aircraft less stable than desired in certain configurations. The system makes the aircraft behave in a similar way to the previous generation of 737 and Boeing seem to have convinced the FAA that it did not need to be covered as a mandatory part of the conversion training. When the system gets an erroneous input from a speed sensor it can misbehave as can any similar system, but you have to know that it exists to be able to do much about it, such as turning it off.
It's based on the fuselage of one 767 type, the wings of another and has some of the 787 avionics; hence the Frankentanker nickname. Using existing components is great, but the higher paid help don't appreciate the effort needed to integrate them so my guess is that some rather optimistic assumptions were made.
