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.

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.

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).

Airport Codes

I managed to find myself in a handful of airports over the last few weeks. Consequently I brushed up on my airport codes, the three-letter abbreviations you often find on boarding passes and data displays. Well, if only I had seen this particular reference from xkcd.

Flying for Thanksgiving

This is a piece from a few years ago, but the New York Times cleverly brought it to the front of their Upshot page. And it seemed just so appropriate. Many of you are likely travelling today—I’m not, I’m headed to work—and many of you will be driving or taking the train. But some will be flying. But to and from where?

The map has some nice features that allow you to selectively few particular cities. Philadelphia has relatively few travellers by air, but that’s probably because places in the Northeast are more easily accessible by road or rail.

Chicago also has relatively few travellers, though more than Philadelphia. I would posit that is because most people are not flying to visit their relatives, but rather driving to places in Wisconsin, Iowa, and Indiana.

No post tomorrow, because I intend on sleeping in. But you can expect something on Friday.

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.

Striking the Balance Between Airline Prices and Service

Yesterday I took a look at the Alaskan Airlines and Virgin America merger. Part of the disappointment on the internets centres around the service and experience delivered by Virgin. I mean who doesn’t like mood lighting, right? Well the Economist took a look at international airlines by both price and service. And if we use Virgin Atlantic as the best proxy for Virgin America, you can see why people prefer it over American carriers.

Merging Alaska Airlines and Virgin America

Alaska Airlines and Virgin America made some news the past few days when they announced Alaska would purchase Virgin America for $2.6 billion. I mapped out the flight routes of the two carriers to see where they overlapped. You can see the results in my piece for the blog today below.

Screening Your Luggage

Another weekend, another weekend trip. This time I’m flying to Philadelphia for a quick trip back home. Naturally, I’m going to pack a suitcase so I can bring some things back to Chicago from civilisation. But what happens to my luggage between my checking it and it being loaded onto the aircraft? Thanks to the National Post, we have a graphic to explain just that.

Germanwings Flight 4U 9525

Yesterday an Airbus A320 operated by Germanwings, a subsidiary of Lufthansa, crashed in the French Alps with no survivors. This morning, I am showing the two best graphics I have come across thus far attempting to explain just what happened.

The first is from the New York Times. In a series of maps, it points out through satellite photography the roughness of the terrain and therefore the difficulty likely to be experienced by recovery crews. The final line chart plots the altitude of the flight, which fell from a cruising altitude of 38,000 feet to just over 6,000 feet in eight minutes. Overall, especially given the limited amount of information that we currently possess, not a bad piece.

The second comes to us from the Washington Post. What I enjoy about this piece is that it combines the altitude chart with the map. This gives a bit context to the fact that despite being still 6,000 feet above sea level, the aircraft was in fact flying into the high mountains of the Alps.

Air Traffic over London

Last week, there was a disruption at the air traffic control centre for the United Kingdom. It caused many travel problems. And the BBC included a graphic showing how the problem was shutting down London air space.
