The A380 is inefficient? I obviously assume you mean relatively. That's an interesting quirk, do you have a source for this wing issue please? I'd like to learn more, as it sounds intriguing

Except one could NOT keep the nose up straight because Boeing's secret trim system had more control authority than the control surface (especially with the one pilot you're suggesting could counteract this).
You're also assuming that they're going to know in time that that the issue they face is runaway trim when lots of warnings going off about other things (like for example an erroneous stall/stickshaker due to the aoa indicator failure causing multiple systems to react/sound). The trim wheel will actuate in normal flight under normal conditions, so those wheels turning isn't somethign the pilots are going to instantly note and realise is what's causing their woe. The nose sinking can also be a symptom of aerodynamic stall.
Of course you already know this, you're just trying to blame the pilots with your trolling. Sadly (for you) you're failing terribly.
Stop digging the hole you're in
Untrue. There was no such decision because the aircraft is not unstable.
In some configurations, within certain parameters, the airframe of the MAX 8 is statically unstable. MCAS fixes that by making it dynamically stable in those situations (as well as change the aircraft handling to more closely ape the 737 classic and also comply with Airworthiness rules about passenger aircraft NOT having positive throttle and attitude coupling). This I would be all for if it wasn't for the terrible implementation of version 1 MCAS. Once the updated MCAS system rolls out it would be an aircraft I would be perfectly happy to fly in.
(Hint: stall is not the same as spin. Stall means "insufficient lift to overcome gravity".)
aerodynamic stall has got nothing to do with gravity. It is when the AoA is such that the airflow over a lifting surface seperates from the airstream causing a sometimes catastrophic loss of lift.
and exceed the envelope fast enough that the main wing stalls, too.
This is actually something that you seem to start alluding to in this sentence I quoted. If you are going to try and throw the pilots under the bus in your continued attempts to vindicate Boeing at least try to explain things accurately
It was erroneously detecting excessive AoA pitch attitude in both of these tragedies, so it most definitely was an active part of this.
You keep saying 'runaway trim' and that the pilots should know immediately that this was their one and only issue, however there were more things going 'wrong' according the the warning and instruments the pilots were seeing than runaway trim. For a start stick shakers and stall warnings which is going to make any pilot hesitant to command less throttle. Just disabling electric trim doen't help if the MCAS system has already commanded full nose down trim since you dont have enough authority with the elevators to correct the max trim, and the aerodynamic load on the elevators means the trim wheels are not going to be a viable means to manually trim the aircraft back to some degree of stable flight. This is why the fix to MCAS includes it having much less maximum trim authority.
I have to say with your attempts to muddy the water relating to Boeing's culpability in this, it rather suits your handle on
so the stick shaker indicating a stall on the cockpit voice recorder, and the warning about stall due to incorrect ias weren't there?
and mister ac, you're parrotting possibly boeing originated untruths in the sequence of events. tell the truth and you may have some credibility
You are blaming the PIC when you do not have all the facts, once fact you are conveniently ignoring is that by pulling the trim breaker you then have to fall back to manual trim, at the already excessive airspeed (the pilot was not going to command reduction of engine power when he had erroneous stall/underspeed warnings) and loading on the horizontal stabiliser. you have very little to no chance to correct the by then already very nose down trim situation due to the fact that you dont have enough enough authority on the horizontal stabiliser trim with the manual trim wheels because of the aerodynamic load on said stabiliser. This combined with the fact that both pilots would have been need to use both hands to pull up on the yoke to try and counteract via elevator commands.
Bottom line:
MCAS in it's then form should not have been let anywhere near a production airframe and it should have had a seperate breaker to disable it rather than having to cut all electric trim. The pilots did not design this doomed to fail system, nor were they given adequate workarounds to the poor design.
I agree, and would add that to assume that they are going to know that it is a runaway trim issue in time to prevent it being an unrecoverable situation is specious at best. There was no proper warning system in place, and there would be the stall warning going off which they would assume is the root of their problems.
I think that, with the circumstances surrounding the loss of 2nd hull due to this (as well as some alleged 'near misses'), the advice of 'just pull the trim breaker' is rather discredited.

Sounds like an interesting material to use, would the wave actionand wind driven sea spray abrade it however?
It only burns if there's no liquid at the point of contact, and what burns is the wick in this situation. As the pg/vg mix is a liquid it has very good thermoconductive qualities. Unless you're running a headbanging mod that raises temperatures to stupid levels the coil should not burn the pg/vg mixture. You would be immediately able to tell from the smell/flavour, just like commercial smoke machines.
The ingredient is there because many people are using eCigs as a way to get off cigarettes.
e-Cigs are safer than cigarettes, albeit not "safe" (to expand on that, because I don't want anyone left with the impression they're safe: Flavored eCigs are almost certainly carcinogenic.
Cite some sources?
They're not pure water, there's carbon based flavoring added, which when burnt creates carcinogenic compounds.
Vaping doesn't burn anything
Are they as bad as cigarettes? No! Obviously not! Cigarettes have more carbon-based material to burn, and nicotine weakens the body's natural defenses against cancer. But they're not "safe" either. What about unflavored eCigs? Well, if they contain nicotine then they're still weakening your body's defenses against cancer,
Cite sources on this too? explain how nicotine on it's own is any worse than caffeine, for instance?
so you're more likely to get cancer than if you didn't smoke or vape at all, just not from the eCig itself.)
Given the choice between kicking the habit, which is hard, or taking something that's much, much, less likely to give you cancer than the regular way to smoke, it's rather obvious why there's a market for eCigs with nicotine in them.
