Southwest 1380

On Tuesday, Southwest Flight 1380 made an emergency landing here in Philadelphia after the Boeing 737-700’s port engine exploded. One passenger died, reportedly after being partially sucked out of the aircraft after the explosion broke a window. But the pilot managed to land the aircraft with only one engine and without any further deaths.

I wanted to take a look at some of the eventual graphics that would come out to visually explain the story. And as of Thursday, I have seen two: one from the Guardian and another from the New York Times.

The Guardian’s piece is the simpler of the two, but captures the key data. It locates the engine and the location of the window blown out by debris from the engine.

The New York Times’ piece is a bit more complex (and accompanied elsewhere in the article by a route map). It shows the seat of the dead passenger and the approximate locations of other passengers who provided quotes detailing their experiences.

So the first thing that struck me was the complexity of the graphic. The Times opted for a three-dimension model whereas the Guardian went with a flat, two-dimensional schematic of the aircraft. Notice, though, that the seating layout is different.

Four rows ahead of the circled window location are two seats, likely an exit row, in the Guardian’s graphic where in the Times’ piece they have a full three-seat configuration. If you check seating charts—seatguru.com was the first site that came up in the Google for me—you can see that neither configuration actually matches what the seating chart says should be the layout for a 737-700. Instead it, the Guardian’s more closely resembles the 737-800 model.

Nerding out on aircraft, I know. But, it is an interesting example of looking at the details in the piece. The Guardian’s piece is far closer to the layout, as least as provided by SeatGuru, and the New York Times’ is more representative of a generic narrow-body aircraft.

Personally, I prefer the Guardian in this case because of its improved accuracy at that level of detail. Though, the New York Times does offer some nice context with the passenger quotes. Unfortunately, the three-dimensional model ultimately provides just a flavour of the story, compared to the drier, but more accurate, schematic depiction of the Guardian.

Knuckle Cracking

I used to work with a designer who was an expert knuckle cracker. So when I saw this article from the Guardian last week, I was hoping that it contained some kind of an illustration. Thankfully it did.

Pop goes the bubble

What I like about the graphic is its simplicity. The illustration does not add a lot of extraneous details in the hands or fingers. Instead it focuses on a three-step zoom into the joint between the fingers and the hands, showing how the bones connect and just what happens.

So Happy Friday, all. Just relax, lean back, and—made you want to crack those knuckles, didn’t I ?

Circle This

Last week I met a friend for drinks and part of our conversation was about how on a trip to east Asia, he flew from New York and then over the North Pole. The North Pole! I then explained it was cool, but not unique. Instead aircraft typically fly between destinations via great circles. Basically, the shortest distance between two points on the Earth is a straight line, but remember the Earth is not exactly flat. Its spherical nature means that the shortest distance sometimes is what you would see as a curve on a flat map. And sometimes, those curves are shortest when plotted over the North Pole, because unlike a flat map, the east and west ends really do connect.

Lo and behold, yesterday the Economist published a piece about a new non-stop flight between London and Perth, on Australia’s southwest coast. The graphic shows the ten longest commercial flight paths. And what do you know, one of the longest is a soon-to-be flight from New York to Singapore that flies near the North Pole.

Great circles are cool.
Great circles are cool.

Of course the key to this type of diagram is the type of projection. Instead of using the Mercator-like map made popular by direction-focused maps like those of Google, here we see an orthographic presentation. It presents the Earth as if we were to see it from space, allowing us to see the fullness of the flight paths. Tellingly, those that appear to cross the middle of the map are shown as straight lines (Atlanta to Johannesburg), but those nearer the edges show the curvature of the great circles (Houston to Sydney).

Baseball: The Bouncier Edition

Baseball is finally back as Spring Training continues to push through March, getting us closer to Opening Day. But one lingering question from last year remains: why the increase in power and home runs? While Major League Baseball (MLB) says there has been no change to the baseball, many think otherwise.

FiveThirtyEight published a piece looking at the insides of eight baseballs, four predating the power surge, which began after the 2015 All Star Game, and three balls since in addition to a newly manufactured and unused ball.

The piece uses a few graphics to showcase the differences, including this cutaway diagram highlighting the different layers of a baseball.

What's inside a baseball?

But the real gem is the X-ray photography done to examine the balls without cutting into them. Thankfully for those of us unfamiliar with x-rays, the designers provided a legend showing the clearly different core densities in the balls.

If you are interested in baseball, and in particular the increase in home runs, the whole article is worth the short read. And if you’re not, well, the x-ray views of baseballs are still pretty neat.

The Sinking of the Vasa

In 1628, Sweden launched one of its largest and most powerful warships not just in Sweden, but in all of Europe. She was to participate in the wars with Poland and Lithuania as Sweden sought to expand her growing empire. After two years of construction in Stockholm’s naval yard she set sail into a calm day with a light breeze.

After a strong gust pushed her hard to port, she righted herself and continued to set sail to a fortress to load 300 troops for the war. But only 20 minutes into her maiden voyage, a second gust of wind pushed her again hard to port so much so that water began to flood in via her open lower gunports. As the continued to rush in, she never righted herself and sank, not to be recovered for 300 years.

The recovery itself is a great story, but the question was why did she sink? This model in the large Vasa museum, built to host the recovered and preserved ship, shows just how dangerously she was designed. Take careful note of the faint blue waves signifying the waterline of the ship and how close they are to the lower gunports.

The short takeaway is that the ship was top-heavy and she needed to be both wider and deeper to support her displacement. I like the model here, but my one complaint with it is the waterline. Even when I was standing in front of it, I did not notice the waves at first. A little bit more emphasis or paint, perhaps to show the water beneath the ship, would really help to convey just how little of the ship was below the waterline.

Farewell, Cassini

Today’s post is a sad post, hence why I did not run with it on Friday. But on Friday, we bid adieu to the little space probe that could, Cassini. This piece is not terribly heavy on the information design, but it does include one diagram—so it counts.

The BBC put together a piece reflecting on the Cassini mission, including its little lander Huygens. If you, like your author, are interested in space-y things, this article is worth the read.

Hurricane Winds

Irma swept the northern coast of Puerto Rico last night after devastating some of the Leeward Islands. What’s next? Well after the Turks and Caicos, Cuba, and the Bahamas we are probably looking at a Florida landfall. (Though in the last 24 hours the track has shifted ever eastward so Tampa Bay looks fine from a direct impact standpoint.)

Harvey was an exception in many ways because most deaths occur not from rainfall flooding, but from the storm surge. Basically a massive wave of water driven by low pressure and strong winds that is literally pushed ashore.

Now even though I just said that, I wanted to talk about the winds for a second. Why? Well it turns out that at 185mph, Irma has some of the strongest sustained winds ever recorded for an Atlantic hurricane. And 185mph winds, they can do quite a bit of damage. How much? Well for that we turn to this illustration from Vox.

You do not want to be around for a Category 5

Assuming the worst case scenario and Irma would strike just southwest of Miami, say Homestead or Key Largo, 185mph winds could do some damage to non-hurricane-safe buildings in a very large American city. And then there is the storm surge, which could be problematic for a city that is already struggling with rising tides. (Thanks, climate change.) The reason I say worst case is southwest of Miami is because hurricanes do most of the their damage—though certainly far from all of it—on their righthand side, which in a northward moving storm would be the eastern half.

The rest of the Vox piece does a nice job explaining Irma, its historic nature, and how it could be so dangerous. Worth a quick read, unless you live in Florida and then you should probably be packing up to evacuate.

North Korea’s Missile Programme

Another week, another batch of news and posturing from North Korea. So I was delighted to see last week a post from Politico exploring the history of the North Korean missile programme with data visualisation.

Shall we play a game?
Shall we play a game?

This kind of maps are my favourite for these types of stories. So often people get locked into this idea of a Mercator or Robinson projection and lines moving right/left or east/west on a map. Instead the world is a globe and the missiles or airplanes or birds or whatever will fly in circles over the poles if it’s easier.

Where Trump Has Travelled

Okay, not entirely. But Bloomberg put together a solid series of graphics tracking not the travels of Donald Trump, but his private aircraft. But that information can serve as a rough proxy for Trump’s travels. But the data is not complete—Russia is missing from the map though he has visited the country for business.

North Korea’s Latest Missile Test

If you missed it—and these days that is entirely possible—over the weekend, North Korea tested yet another missile. It did land very far away as it fell just off the coast of North Korea near Russia.

But it did travel far enough away to be of concern. Why? Well, this print graphic from the New York Times does a great job showing what that missile test really tested.

Creeping towards the West Coast

I want to end on a geography lesson for Attorney General Jeff Sessions. Those little dots in the upper right part of the circle? Those are the Aleutian Islands. They are like that island in the Pacific known as Oahu, which is part of the state of Hawaii. The Aleutians are part of the state of Alaska, which is, you know, one of the 50 states. Just trying to help you out, sir. So if you ask why we care about defending those islands in the Pacific, well now you know.
