    A single engine failure can crash a twin engine plane -- if it happens at the wrong time and the pilot fails to initiate the documented corrective action. That's the case with a LOT of failures. After the Lion Air crash, every 737 MAX pilot knows how to detect an deal with that problem so there's no excuse for a repeat (if the Ethiopian Airline crash was a repeat - which I'm not confident of given the witness reports that the plane was on fire on the way down to the crash site).

    There are two AOA sensors on the 737 MAX - one on each side. The erroneous one may give a rational, yet wrong, signal. However, I suspect that the Boeing "patch" will add cross checking and perhaps more explicit alerts to the pilots when something seems "off".

    My lay person's understanding...

    In order to increase fuel efficiency on the 737 MAX, the engine fan diameter was increased. These "underwing" engines would have been too close to the ground if mounted as on other 737 models. Thus, the engineers moved the engines forward and upward to achieve necessary ground clearance. This, along with some other changes, moved the force of thrust forward which made the plane more prone to lift its nose too high and stall. To guard against this, Boeing introduced the Maneuvering Characteristics Augmentation System (MCAS) which activates automatically when the autopilot is off in some conditions which include when the angle of attack (AOA) is too high. The MCAS system, when needed, attempts to prevent a stall by adjusting the horizontal stabilizer trim upward and will do this over, I believe, about 10 seconds or until the pilot overrides it or the angle of attack is within limits. If the pilot activates the trim control switch on the yoke, MCAS will be disabled -- but, five seconds after the switch is released, MCAS will reengage if the conditions call for it (esp. AOA). When MCAS is altering the trim, the manual trim controls on each side of the center "console" will be spinning away and, if a pilot looks down, they will see that motion as there is a white stripe extending outward from the center in order to make the movement obvious.

    The best speculation I've heard about the Lion Air crash was that there was a problem with one of the AOA sensors. There are two such sensors - one on both side of the 737 Max.

    As in most crashes, due to the redundancy of systems and procedures, it's rarely one thing that causes a crash but rather a cascade of events.

    There had been problems with at least one of the AOAs on previous flights but maintenance attempts appear not to have solved the problem. So, first there was a failure of maintenance, but of course AOA sensors will fail from time to time, so one can't blame the crash on that failure.

    I've not heard how MCAS handled conflicting AOA sensor readings but I suspect this is one of the big areas of change that they will push in the April "patch". But, it's likely that the failing AOA caused the MCAS to activate when it shouldn't have and push the nose down by adjusting the trim - but this actually pushed the plane's nose down too far. When the pilots tried to correct, they ended up disabling MCAS (although perhaps not explicitly aware that they were doing so) only to have it start undoing what they had accomplished five seconds after they released the trim control on the yolk - and this was a vicious loop.

    Had the pilot recognized what was happening, they simply would have ran the "runaway trim" procedure (which would have disabled MCAS and some other automatic trim controls completely via a switch on the center "console") and flown the plane manually with no problems. Unfortunately, the pilots likely didn't figure out what was causing the problem and failed to execute the necessary procedure. So, that was a pilot error (and, that's probably what will be determined to be the main problem here, with contributing factors).

    There is much debate on why the Lion Air pilots may have failed to recognize what was going on. Many pilots and their union claim that they were not told about the existence of MCAS. Boeing hasn't been talking a lot, but they seem to assert that there was no need to train the pilots on MCAS beyond what the manuals/training did as it was a classic "runaway trim" scenario and the training was sufficient to cause the pilots to detect that case and initiate the proper procedure. Boeing did, however, issue documentation updates to operators worldwide soon after the Lion Air crash.

    After Boeing issued the documentation updates, every 737 MAX pilot should have been fully aware of MCAS and what to do if was doing the wrong thing. This, coupled with the witness reports that the Ethiopian Airline 737 MAX that crashed was spewing smoke and fire from the back of the plane a

    I've known Software Engineers that had zero interest in being "leaders" or "architects" - perhaps because they eschewed conflict, were somewhat antisocial, didn't like being responsible for other peoples' work, or just didn't like doing that sort of work. However they were absolutely awesome at some particular aspect of their job such as having an unparalleled ability to track down and eradicate concurrency related heisenbugs which occur extremely rarely and leave core files that are quite inscrutable. These bugs can hold up releases by months, piss off Fortune 50 customers who have spent big bucks on your product, and harm the reputation of the company. Noticing and resolving them quickly (hopefully before Alpha) is generally far more important than any new feature in a release.

    No one is required to agree to a TOS on a commercial website and, if they wish, they can have a lawyer review the TOS before agreeing.

    In reality, I think most people (excluding those who are illiterate, and/or suffering from some forms of mental illness, and/or intellectually disabled) are just too lazy and/or unmotivated to read and understand most TOSs rather than "unable" to do so. Note that having to look up a phrase in a dictionary doesn't mean you are unable to understand a document containing that phrase -- and the next time you run across that phrase you then already know what it means. Note that having to refer to Section (x)(1)(II)(A) of a contract when it's mentioned by reference elsewhere in the contract may be time consuming, but it does not render the one "unable" to understand the contract. Long ago I used to read TOSs all the way through and never had a problem understanding them. Occasionally, I will still read one all the way through just to keep tabs on what tends to be in them and still have little trouble understanding them -- yes, it's a lot of work and if I actually insisted on reading every one, there are a lot of sites I wouldn't patronize as the cost of reading and understanding the TOS far exceeds the value of the site to me (although not, perhaps, to others).

    Although, of course, I can't predict reliably how a court may interpret potentially ambiguous terms. However, the simpler the agreement is, the more likely there are to be ambiguous terms. For example, does the term "supplier" just refer to the subsidiary providing the service or does it apply to successor companies and parent company? Much of the complexity that makes a TOS harder to read is attempting to eliminate ambiguity -- as is the case in most legal documents. If the TOSs were more easily read, the resulting ambiguity would result in more class actions suits attempting to exploit that ambiguity.

    Courts tend to apply the doctrine of contra proferentem to contractual interpretation, especially in contracts of adhesion ("take it or leave it" or "standard form" contracts) or in situations where the drafting party has more power and expertise than the non-drafting party (both true in the case of most TOSs). Under this doctrine, ambiguous terms/clauses are interpreted in favor of the non-drafting party. As a result, the drafting party must be very careful to remove any ambiguity that could be interpreted against them -- and this results in much more complex contracts.

    Note also that "being unable to understand a contract" is quite different from "preferring that a contract's terms were different".

    I don't recall commercial airlines delaying flights simply because a passenger never checks in (either themselves or their luggage - which I assume is the case here). It happens on most every flight and that's why if a flight is fully booked on a large plane, it will almost always end up with standby passengers. The passenger's actions certainly didn't inconvenience other passengers -- they have no idea the seat was booked.

    The one exception I've seen to the delaying for one or more passengers is when those passenger have an incoming connecting flight and that flight is delayed. In that case I've seen outgoing flights held for a while so, yes, if the passenger just takes his carry-on (having no checked baggage) from the incoming flight and never appears for the outgoing flight, that flight might have been delayed longer than if he had traveled on through. Of course, I didn't RTFA so I don't know if that happened here.

    Suppose I buy a gallon of milk from the store knowing that I'm only going to use three quarts of it but the one-gallon package is cheaper than three one-quart packages (or one half-gallon package plus a one-quart package). I do this knowing that I will throw out the last quart (perhaps I have very regular "milk usage requirements" and know that I'm scheduled to go out of town for a few months after only consuming 3/4 of the gallon package). Did the dairy or the market suffer any economic damages from my decision not to use the "last leg" of the milk and take advantage of volume buying?

    Sure, the market and I don't have a contract, but even in a breach of contract case, the aggrieved party is generally only due their actual damages.

    I didn't get that either so I did the unthinkable - I skimmed the article and found this (before I gave up)...

    Some university leaders said they were concerned that certain measures taken to address surging student demand may disadvantage people who are already unrepresented in computer science — including women, African-Americans, Latinos and low-income, first-generation college students.

    Some universities now require incoming students to get accepted into computer science majors before they arrive on campus — and make it nearly impossible for other undergraduates to transfer into the major. That approach can favor incoming students from schools with resources like advanced programming courses. It can also favor male students — because women on average are less likely to have taken a computer science course in high school.

    “When you put any kind of barrier in place in terms of access to computer science majors, it tends to reduce the number of women and students of color in the program,” said Maria Klawe, president of Harvey Mudd College, a private college in Claremont, Calif., that has become a national model for diversity in computer science.

    Although, it seems any decision on the part of female students to eschew available computer science courses in high school isn't a "problem". Surely very few, and no public, high schools let boys take such classes while preventing girls from taking them. Perhaps girls and boys tend to choose different courses in high school, but that's a free will choice of each student.

    Similarly, I don't see it as a "problem" that women are under represented in commercial fishing and logging (two of the most dangerous professions in the country) or in plumbing and construction laborer (dirty and hard jobs respectively) -- I don't see a lot of women clamoring to get into these fields and finding that they are excluded based on gender (vs. strength or willingness to take physical risks or willingness to get dirty and work in unpleasant weather conditions -- all of which would be their choices).

For example when JFK said "We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard...", he hadn't gotten approval in the budget for all funds necessary to do so.

Second, I didn't see any requirement that a "manned" space flight to Mars even required that the person survive past launch - in fact, I'll bet you could find some rich terminally ill person who would happily pay to launch on a flight to Mars with just ten days of supplies (O2, food, water) and a "sleepy pill" (or helium or nitrogen -- whatever works best) to use just before the O2 ran out. Given the way Trump makes deals (even when in the rare instances where he keeps his side of the bargain), one should just ask what fine print is in the agreement before claiming attempting such a mission by 2020 is not possible.
