Thanks, I was only going off the nutrition label, it shows 60% RDA per sheet. However, the reference link for the academy is broken; I wonder if they’ve changed their stance? Other references indicate raw nori has B12 but the drying process

"Boeing" is not a cause. Things like their safety culture can be a cause, or lack of good process control can be a cause. The reason why Boeing is catching a lot of flack is because they deviated substantially from best practices.

I disagree. The media has covered the training (or lack of it) extensively. It seems like you want to point to a singular cause. As with most mishaps with complex systems, it’s the result of a cascade of failures. Training is only one part

As an example, you said they “ignored” the over-speed warning. I would bet it’s much more likely that there was too much going on in the cockpit, likely with confusing or conflicting information, that prevented them from making the correct

Importantly here, Boeing doesn’t require licensed engineers because they operate under an industrial exemption.

Mark Forkner was a pilot charged in the MCAS debacle (and acquitted).

You can also read the Boeing documents. The hazard analysis listed MCAS as hazardous. By Boeing process controls, that should have mandated redundant sensors. Why were they optional? Because that could increase profits. (Seattle Times has

Ehhhh it’s not always the case. Lots of laws have low levels of support (from constituents) but high levels of inertia that prevents them from being repealed. Subsidies are a prime examples. Alpaca subsidies for the Korean War were not repe

For a relatively brief period, I worked as a software quality engineer related to aerospace research and development. Practically every test that used software required a “go/nogo” decision before they were allowed to run any safety cr

When you avoid accountablilty, you pervert the risk/benefit. So people get incentivized to roll the dice on low-risk/high severity events because most of the time, it will come out in their favor and they can continue cashing thei

They aren’t in these industries. Relatively low-level engineers have the capability (some would say duty) to stop work. Typically, they have a different chain of command for that very reason.

Yeah we both agree that the decision isn’t “kill/not kill”. It’s much more ambiguous and murky, especially when dealing with low probability events. That’s why it takes expertise, but it doesn’t mean there shouldn’t be accountability f

Not to "kill their users" but they realistically have meeting to vote on whether the system is "go/nogo". This is the basic structure of many aerospace designs. If you ever watch a rocket launch, they are literally

The article links to a USSOCOM-funded study. In your opinion, are they (as a whole) seriously concerned with mitigating this issue or is it just checking the box? The worry is this can be similar to the buried diesel tank issue contaminatin
