You should always question assumptions. Especially when millions of dollars are being spent searching. Do you have the data, the calculation of this arc, and the review of this method or not?

Do you think its strange that all the debris has washed up on the opposite side of the Indian ocean to this arc?

I am not in this industry so I am curious, what has been implemented if anything to prevent losing another plane is such a manner? have there been any general changes to requirements for airliners or crews?

I'm of two minds on the use of scrolling as a method of interaction with the page. The term "scrolljacking" has been coined as the negative way to describe this particular style where the page itself is designed to render based on the scroll position. At the same time, I'm completely behind trying to find new and more effective ways of interacting with content.

To me, this page is mostly effective, but I'm on a Macbook Pro, which is probably the best-case viewing experience, but I can't imagine this working well on older mobile devices.

This is the most annoying page design/behaviour I have encountered in the last 30 days. I am very curious, but I just can't.

I don't understand this at all. You scroll, and new text appears and the map in the background simply shifts to different points and shows some different data. This seems exceedingly simple to display all the data they wanted.

That's really neat. Jump down to the "Phase Two Data", they found some really cool stuff down there. Whale bones and ships and cable.

I would love to, but the site is basically un-navigable.

The debris took a long time to appear. That fits perfectly well a scenario where the plane crashed on one side of the ocean and the debris washed up on the other side.

I think the point is that the page designers want to show me a movie, while I want to read an article.

It's annoying, because the fate of this plane is far more important to me than tedious details of web design. But I find the page incomrpehensible and will have to learn the facts somewhere else.

literally the only mode of interaction to consume the content is "scrolling down with your mouse" and this is apparently beyond your capabilities of comprehension?

Yes, it has been published. See Inmarsat's post on their reasoning, based on AAIB data at [0] and the WIki page [1] also has a good summary. The peer reviewed paper [2] by Inmarsat is also available from the Journal of Navigation.

There's a lot of comments claiming the site is "un-navigable" which I find to be curious given that the only thing one has to do is scroll down

And this is coming from a person who is not into the whole "scrolljack" thing to bring things into and out of view. Its implementation here is a bit hokey, but that's the state of web UI these days. I was able to see all the information, I can say that at least.
