Air traffic data is great fodder for visualizations. Case in point, this lovely animation of a day of flights titled "North Atlantic Skies" by air traffic control firm NATS. (via Laughing Squid) Read the rest
Why do birds fly in a "V" formation? Scientists at the UK's Royal Veterinary College attached sensors to endangered ibises migrating from Austria to Tuscany. What they confirmed is that the aerodynamics of V flocking helps the birds conserve energy and that they optimize this by careful positioning and timing their wing flaps.

The Solar Impulse plane project president and pilot Bertrand Piccard lands after a 19-hour flight from Madrid at Rabat's International airport, June 5, 2012. The plane landed in Morocco on Tuesday, completing the world's first intercontinental flight powered by the sun to show the potential for pollution-free air travel.
A family from Washington state had to cancel an island vacation when their flight was grounded after their 3-year-old son pitched a tantrum.
The toddler had been quietly playing with an iPad while waiting for the plane to take off, the father said. When the iPad was taken away—you know how all electronics must be stowed during takeoff and landing—all hell broke loose. Read the rest
A Solar Impulse aircraft takes off at Payerne airport May 24, 2012, piloted by André Borschberg. The Solar Impulse HB-SIA prototype aircraft, which has 12,000 solar cells built into its jumbo-jet-sized wings (about 200 feet long), attempted its first intercontinental flight from Switzerland to Morocco with a few days for a technical stop and a change of pilot in Madrid. This flight will act as a final rehearsal for the 2014 round-the-world flight.
As I noted in a Boing Boing post yesterday, there's news of a possible change ahead for in-flight gadget rules in the US.
The Federal Aviation Administration currently prohibits passengers from using electronic devices on commercial flights when the plane is below 10,000 feet in altitude. But the FAA announced this week that after widespread demands to modify restrictions, there may be new efforts to review whether devices like the iPad or phones in "airplane mode" can be permitted safely during takeoff and landing.
Aviation journalist and pilot Miles O'Brien, who uses his iPad for navigation while flying his own plane, joined KPCC's Patt Morrison show today to discuss the news. Here's a direct MP3 link to the radio segment. It's a good listen. Read the rest
One of the most common arguments you'll hear against evolution (or, at least, one of the most common arguments I heard growing up amongst creationists) had to do with transitional forms. An eye is a valuable thing, this argument goes. But half an eye? That's just a disability.
Like many of the really common arguments against evolution, this one crumbles the minute you start to apply the slightest bit of fridge logic. Sure, half an eye is less useful than a full eye. (Or, more accurately, a clustering of light-sensitive cells don't have all the functionality of a modern eyeball and optic nerve system.) But, if most of the other creatures have no eyes, and you have a few light-sensitive cells, you've got an advantage. And an advantage is all it takes.
Now apply that to the evolution of birds. One of the cool things about this process is that it appears that feathers evolved before flight. In fact, feathers seems to have evolved rather independently of flight.
You might ask: What's the point of that? How are feathers an advantage if they can't help you fly? Is this just about looking pretty? Maybe. But on his blog, The Loom, Carl Zimmer presents another hypothesis. Feathers and wings, even without flight, might have given their owners a physical advantage over bare-skinned cousins. The birds in this video aren't flying. You can see that their feet don't leave the ground. But the act of flapping those feathers around helps them to walk up inclines that would otherwise be impassable walls. Read the rest
Over at New Scientist, Paul Marks speculates that "the long-awaited ability to use a cellphone or Wi-Fi connection on an aircraft might become a casualty of the latest aviation security threat."
It is not yet known whether the cellphones in the printer bombs were intended to be triggered remotely. They may have been intended simply as timers, as in the 2004 Madrid train bombings. But future devices could take advantage of wireless communication.Aircraft bomb finds may spell end for in-flight Wi-Fi (New Scientist)
In-flight Wi-Fi "gives a bomber lots of options for contacting a device on an aircraft", Alford says. Even if ordinary cellphone connections are blocked, it would allow a voice-over-internet connection to reach a handset.
"If it were to be possible to transmit directly from the ground to a plane over the sea, that would be scary," says Alford's colleague, company founder Sidney Alford. "Or if a passenger could use a cellphone to transmit to the hold of the aeroplane he is in, he could become a very effective suicide bomber."
So what's a curious guy to do? To the Internet! Which is exactly what I did. Responses starting pouring in. Including one from a pal at the State Department, who echoed my basic goal: To use video chat to tuck my kids into bed isn't a crime. Or at least, shouldn't be.An FAA guidebook says inflight video chat is to be discouraged because it can be annoying to seatmates, but that's very different than banning something because it's a terrorist weapon.
The flight attendant just showed me the United policy manual which prohibits "two way devices" from communicating with the ground. However, the PLANE HAS WIFI. To combat this, not unlike China, United and other airlines have blocked Skype and other known video chat offenders. Apparently, they missed Apple iChat. Oops.
