For White Board MBAs.

Get this: 
(Reuters) - Boeing Co has abandoned a key automation system used to make fuselage sections for its 777 jetliners amid reports of reliability issues, and will instead partially switch back to mechanics, the planemaker said on Thursday. The company began to build 777 fuselages in 2015 in an upright orientation, with robots drilling holes and installing fasteners, an initiative known as fuselage automated upright build (FAUB). The world's biggest planemaker said it had stopped using the system which, according to industry sources, caused problems with reliability and rework issues. Boeing had faced delays last year when the FAUB machine was tried out on existing versions of the 777. Instead, the company will switch to "flex tracks" - an automated method to drill the holes along the circumference of the airplane that are then fastened manually.
Believe me, there is more to it than meets the eye. By far, I underscore it, by far not all things could be done by manipulators (aka industrial robots) and especially so in the aerospace industry where only humans can provide for a foreseeable future required input and actual quality control. Training, qualifications, education become a decisive factor. I will not disclose any secret that many companies in aerospace prefer human layup of aircraft composite parts to any "machine laying", granted that machines can do only few and less complex parts anyway. And then comes the issue of Quality Control. Yes, there are machines involved in it, many machines, some of them very sophisticated, but in the end it comes down to human supervision and decision making process that define if the aircraft flies or it fails. It is good news that Boeing made this decision--in the end, it is Quality Inspector who answers for the aircraft, not some machine which can do only so much. 

This brings a larger issue to the fore--naked numbers on "robotization" which all kinds of white board trained MBAs love to operate with, in no way defines the "strength" or otherwise of economy. Robots are useful and they will continue to be deployed but they are merely tools and sometimes can be harmful due to bad engineering and design. Boeing provided today an excellent example of that. It is one thing to drill a substandard hole in a car on the conveyor, totally another--to do so on a commercial or military aircraft. Lives of people who fly it, including those on the ground, depend on that and no amount of bookkeeping and abstract economic data can ever substitute ethical and professional attitude of people making planes. This is a real hi-tech I am talking about, not assembly of iPhones or CGI. Only designers, engineers and, in the end, production floor manufacturing specialists can have a decisive input on the production issues.

This Is Not Good.

WSJ reports:


Boeing Withheld Information on 737 Model, According to Safety Experts and Others 


This is more than just "not good", this is down right scary.
The automated stall-prevention system on Boeing 737 MAX 8 and MAX 9 models -- intended to help cockpit crews avoid mistakenly raising a plane's nose dangerously high -- under unusual conditions can push it down unexpectedly and so strongly that flight crews can't pull it back up. Such a scenario, Boeing told airlines in a world-wide safety bulletin roughly a week after the accident, can result in a steep dive or crash -- even if pilots are manually flying the jetliner and don't expect flight-control computers to kick in. That warning came as a surprise to many pilots who fly the latest models for U.S carriers. Safety experts involved in and tracking the investigation said that at U.S. carriers, neither airline managers nor pilots had been told such a system had been added to the latest 737 variant -- and therefore aviators typically weren't prepared to cope with the possible risks."It's pretty asinine for them to put a system on an airplane and not tell the pilots who are operating the airplane, especially when it deals with flight controls," said Capt. Mike Michaelis, chairman of the safety committee for the Allied Pilots Association, which represents about 15,000 American Airlines pilots. "Why weren't they trained on it?"
Make no mistake--I am all for automation, where it is needed. But I am also, and primarily so, for high level of professional training of personnel which provides a set of fundamental skills allowing professional pilots, mariners, surgeons, what have you, to be independent of "technology" in critical situations while deciding when and how to engage it. We just saw another example of a loss of a situational awareness and of extremely low level of fundamental professional skills here:


At least in Norway no people got killed, in case of Indonesian Boeing every one on board died. Somebody at Boeing has to answer for this major FUBAR and higher-ups there at least may try to remind people who write all kinds of software for commercial aircraft that it is not a freaking video-game they are coding--people's safety is at stake. But that opens another can of worms altogether--technophilia taken to the extreme in a firm conviction, primarily among people who do not have required complex skills such as piloting, that machines can do everything for us. They can't, and they shouldn't. In the end, the Miracle on Hudson occurred primarily for the reasons of Chesley "Sully" Sullenberger and his crew's superb professional human skills under the conditions of almost complete failure of technology. In the end, I would be extremely apprehensive while being flown in the aircraft in which pilots are merely operators of the cockpit at the service of main on-board computer, or to be driven in pilot-less cars--another wet dream of office plankton who thinks that human lives can be described in Java or C++. 

Most of all, I  would be very, and I am, apprehensive of exclusion of a human professional from the decision loop in Combat Informational Control Systems (aka Battle Management) responsible for the use of sensors and weapons because in this case a Skynet scenario becomes not only possible but reasonably probable. In warfare, I am all for networks and AI but only under conditions of a human having his hand at the switch. I really hope that Boeing learns its (tragic) lesson because I like Boeing's aircraft but the idea that those could become simply uncontrollable pieces of metal with no ability to get them under control is, frankly, terrifying.
