Yup. Moving those engines forward to make clearance was a change
that really narrowed the CG box. My own thought was to figure out
a way to make the landing gear longer without affecting the CG. Oh
well. They made their bed...

The original plan was to start working on designing a new plane,
but they were afraid of losing business to neo so the engineers
were told to make it work. In order to do this, they pushed the
engines up and mostly in front of the wing which pushed CG
forward and moved center of thrust. This lead to a plane that
needs a much narrower flight envelope, i.e it doesn't want to
fly in a lot of attitudes where a real 737 is fine.
Why do you believe it is inherently flawed?
It is a 737, the airframe with the best track
record on the planet.
It is too bad they did not have a voting/contention
algorithm between the two angle of attack sensors and
chose to only use one as the authoritative source.
That was a boneheaded coding decision. The other
sensor had live data on the network that was there for
the using.
It is too bad the pilots failed to absorb the
training update telling them to switch off the system
when it was causing control inputs that were obviously
wrong.
It is too bad the pilots did not simply switch it
off. I have had runaway trim motors try to do this to
me before and that is something you learn during
primary training.
Even then, you can recover almost all upsets with
“push-power-rudder-roll-climb”.
It is too bad that Boeing did not immediately tell
operators to cease using that system after the first
crash.
But this is just one system amongst hundreds on the
aircraft, all tried and true for many years.

The Max is inherently flawed and I'd
generally say don't bet on things with inherent
flaws. Think F35 and how long it took to get that
kind of sort of right. The CG is too far forward.
Perhaps if they stretched the aft section a little
and swept the wings back a little but then it
wouldn't be a 737 anymore.
I have an idea of building up a list of ISPs
with rural exposure and shorting them because
Sarlink is going to blow up a lot of their
business model. In particular, I'd look for
double play ISPs with ARPU above about 75.
Boeing is going to have a good year.
The MAX 737 saga is coming to an end and
their while system will be better because
of it. And then it will be forgotten.
Just like VW emissions testing...
Even so, I am going to stick with my
super high priced index fund. It is at a
historical high and I still dumped more
money into it.

Something like 6
months ago my financial advisor
convinced me to sell my GM stock and
buy Boeing. I’ve suspected I did
something stupid ever since. Getting
out of GM was probably OK, but I think
Boeing has plenty of room to drop. I
am afraid investors may dump BA as end
of year approaches to clean up their
portfolio or take tax losses, and in
any case, they are not looking like a
well run company.
So if you want to
double down on your Moviepass
adventure, you could buy a bunch of
Boeing.
Or how about
Frontier Communications? A bargain at
less than $1. 5 years ago they were
at $100. Bloomberg article a couple
days ago says they are looking for a
new CEO ahead of an expected
bankruptcy filing. Which was totally
predictable when they took on a
mountain of debt to buy all the areas
that Verizon and AT&T didn’t
want. It has to be bottoming out. No
where to go but up, right?
I
am thinking of following up my
strategic Moviepass investment
with one in PG&E. It has
to be bottoming out. No where
to go but up, right?
