Wi-Fi in the Sky 148
mindless4210 writes "In an attempt to have the greatest warflying run to date, members from Daily Wireless, Tom's Hardware, SoCalWUG, and Highlands Highspeed teamed up for an amazing two-plane mission around Southern California. They picked up over 3000 access points and 900 clients, established a point to point link between the two planes, and successfully video conferenced in real time over the connection. This is also the first time that the wireless network detection tool Kismet has been taken up in the air, reporting over twice as many APs as NetStumbler. There is some footage of the flight in divx format available here."

Indicated Airspeed and True Airspeed. True takes into account the wind, if you have a tailwind you can be going faster than the aircraft is possible of flying, like when the B-29s discovered the Jet Stream over the Pacific and would end up going 450-500 MPH when the aircraft was only possible of doing around 290 under it's own power.

WEP (in)security assumptions (Score:5, Interesting)
As a starting point, the WaveSEC [wavesec.org] homepage describes a way to secure a wireless network entirely using IPsec, without relying on WEP. In addition, for a small home network you can get away with static IP addressing instead of using DHCP, and in this way you can gain all the benefits of WaveSEC security without needing any software patches (since if you look closely all the software patches are DHCP related).
IPsec is supported in Windows 2000 and up, Linux 2.6 (natively) or 2.0 and up (with Free S/WAN patches [freeswan.org]), and FreeBSD; unfortunately I have no firsthand knowledge of MacOS support. The main drawback of IPsec is that it is a very complicated protocol and takes a lot of effort to set up. Making different systems interoperate with each other is especially challenging -- for this task, I recommend the Free S/WAN interop page [freeswan.org] which links to an eclectic pile of guides covering most of the possible combinations.
My own home wireless network is a mix of Linux and Windows XP clients all connected via IPsec, and I have much more confidence in its security than I would otherwise have with WEP.

The ONLY security WEP provides is merely delaying any would-be 'hacker'.
Simply sit within the range of a wireless network with your laptop, collect enough packets with Ethereal or a similar tool, and you'll have the AP's WEP key.

I agree that for most people (and maybe even for me), WEP is good enough. However I should point out that I did actually spend a night cracking my own access point's WEP encryption and my success in that effort is what motivated me to seek a better solution.
My bigger objection is with the article's premise that the unWEP'd networks are automatically insecure. WEP is neither necessary nor (fully) sufficient for really good security. People who really know what they're doing don't actually use WEP. The writers of this article (and many other writers) present a very simple "TURN ON WEP" message that does not adequately convey the subtleties of what is in fact a very complicated security situation.
I don't necessarily expect a sermon in every article, but I would appreciate a more moderated message and at least some kind of acknowledgement that there is more going on behind the scenes.

While sitting at my coffee table, Kismet shows 4 wireless networks available (without an external antenna) and each of these networks has WEP enabled, the message must be getting through to some people!
I know absolutely nothing about Microsoft's WI/FI API, but imagine a virus that spreads throughout the mess (er, mesh) created by the unsecured wireless networks. Hmm... and if the virus is smart enough to determine the WAP's manufacturer, it could even use the default admin password to blow massive holes in the router's firewall as well. While it's not very likely in my geographic location, it could definately be feasible in more densely populated areas.
Oh, and kudos to Kismet for blowing NetStumbler out of the water!

Doors pop open all the time. During flight training, flight instructors tell students what to do in the case that a door pops open. It's actually not a big deal, if you have the proper training. The air pressure keeps the door almost closed.
Inexperienced pilots flying formation?? Do you know what kind of formation we were flying? Did you know that both pilots have hundreds of hours? The pilot of the Cherokee has a private airstrip with 5 planes and a helicopter.
The closest we ever got to each other was about 100 feet. Most of the time we were at least 300 feet away.
As far as the wifi messing with the avionics. Yeah there is a chance... but I did a previous warfly in December, 2003. We didn't experience any problems. Also, it doesn't really matter if the wifi messes with avionics, as we flew VFR. We followed visual landmarks, and used a moving map GPS.

What the hell is that supposed to mean? Even on a commercial scheduled flight, any electronic device at all that the pilot and/or carrier deems safe is allowed--and that's under IFR. For GA craft under VFR, there's nothing even remotely illegal or even discouraged about it. There's obviously nothing dangerous about it. Steam gauges, visual navigation. You could lose your whole electrical system in those conditions and still continue the flight safely and legally as planned (albeit not in LAX's airspace) The 2.5 GHz transmitters aren't going to interfere with the com radios, though--you could test that on the ground. Hardly the stuff that would put lives in danger. Did you read your FAR/AIM manual before you took your written test? I did. Yep, the whole damn thing. And let me tell you, there's nothing illegal about what they did.
* Unexperienced pilots flying formation
That would be dangerous if they were inexperienced. But how did you arrive at that conclusion? Certainly not by checking the FAA registry -- At least one of the two is an instructor.
* DOOR POPPING OPEN AT TAKEOFF
A bit out of the ordinary, sure, but certainly not the stuff of disaster. The Cessna is, after all, a 1973. Perhaps the door latch needs work. Still, an open door has never caused an accident on an unpressurized aircraft. Never? Never. Not even one. Sometimes the pilot forgets to fly the plane when he sees that the door is open. But that's just training.
No, I don't see anything inherently dangerous about the operations they were conducting. Actually, I think you just came up with a few objections to their procedures to find an excuse to let the slashdot world know that you're a pilot.
