The 777 has water separators that routinely capture and remove liquids other than fuel. I work in the noisiest WiFi environment possible, many APs sending full power, we don't even get interference on analog headphones, there's just not enough power. This article reminds me of Professor Mike Hennel's rush to blame software when Air France parked an A320 in the woods, turned out it was idiot pilot, though I don't expect that's the case here, the similarity the that bogus 'experts' get air time to pursue their favorite theory. If a cell phone in a plane does nothing and they can fly past megawatt radio transmitters with impunity then I don't expect the few microwatts that might have reached the aircraft from a WiFi AP could do anything.]]></description><dc:creator><![CDATA[Chris Hann]]></dc:creator><pubDate>Jan 22nd 2008 11:27AM</pubDate></item><item><title><![CDATA[Comments on Was Wi-Fi Behind the Boeing 777 Crash In London?]]></title><link>http://www.switched.com/2008/01/22/was-wi-fi-behind-the-777-crash-in-london/</link><guid isPermaLink="true">http://www.switched.com/2008/01/22/was-wi-fi-behind-the-777-crash-in-london/</guid><description><![CDATA[Oops. Misread that. The fuel/water description in the article is correct. But the 777 routinely deals with fuel contamination, it would have to be something very similar to fuel to escape the separators, but then it would mix instead of sitting in the tanks. AAIB and NTSB are looking at computer faults.]]></description><dc:creator><![CDATA[Chris Hann]]></dc:creator><pubDate>Jan 22nd 2008 11:36AM</pubDate></item><item><title><![CDATA[Comments on Was Wi-Fi Behind the Boeing 777 Crash In London?]]></title><link>http://www.switched.com/2008/01/22/was-wi-fi-behind-the-777-crash-in-london/</link><guid isPermaLink="true">http://www.switched.com/2008/01/22/was-wi-fi-behind-the-777-crash-in-london/</guid><description><![CDATA[We must understand, that an author is not an expert, unless they have a Degree in what they are writing about. A pilot is not an expert in electro-magnetic fields. An author has a book to sell. In Nina Anderson's case over sixty books on everything from diets to a 2012 dooms dayer. I will wait for an expert to really tell us... Looks like to me Nina is an expert on selling herself and her books.]]></description><dc:creator><![CDATA[Thom Lengyel]]></dc:creator><pubDate>Jan 22nd 2008 11:55AM</pubDate></item><item><title><![CDATA[Comments on Was Wi-Fi Behind the Boeing 777 Crash In London?]]></title><link>http://www.switched.com/2008/01/22/was-wi-fi-behind-the-777-crash-in-london/</link><guid isPermaLink="true">http://www.switched.com/2008/01/22/was-wi-fi-behind-the-777-crash-in-london/</guid><description><![CDATA[Was Gordon Brown's aircraft equipped with Electronic Counter Measures? (starting up as the 777 crashed).

The probability of bad fuel getting to both engines at the same time is, for all practical purposes, zero. There was fuel on-board so a fuel exhaustion scenario can be ruled out.<br><br>So, how do you command both engines to shut down if the pilots didn’t do it? Easy, the flight-control system likely told the engines to shut down and they properly obeyed. Normal shutdown involves opening the guard on a guarded switch and then turning it off. Nowadays, such switches are not really switches, but addresses on a bus. Somehow the triply-redundant flight-control computers determined that the switches were turned off. Note that three identical computers, all running the same version of software, do not constitute a triple-redundant system! Boeing’s 777 website does not even discus this issue. Perhaps the flight-control system is not triple-redundant because it has mechanical override capabilities –except for the engines, of course, --oops!<br><br>]]></description><dc:creator><![CDATA[Richard B.

What was wrong with his car was it also hit?? He said it was a dead battery??<br> <br>Somebody check if the path the PM took to the airport would line up with the 777 at the time it happened.<br><br>If it was a EMP they are never ever going to say so.<br> <br>We are using computers way to much in places that they are not needed. We are risking lives on parts that a little static spark can destroy.<br> <br>This kind of thing has happened to aircraft but it will never be in the news. <br>Remember the cops have things that can burn out electronics in the cars we have today.]]></description><dc:creator><![CDATA[John]]></dc:creator><pubDate>Jan 22nd 2008 5:13PM</pubDate></item><item><title><![CDATA[Comments on Was Wi-Fi Behind the Boeing 777 Crash In London?]]></title><link>http://www.switched.com/2008/01/22/was-wi-fi-behind-the-777-crash-in-london/</link><guid isPermaLink="true">http://www.switched.com/2008/01/22/was-wi-fi-behind-the-777-crash-in-london/</guid><description><![CDATA[I read this earlier, and couldn't believe it was considered a 'headline' at CNet.  Basically, an obscure author struggling to sell her book on the dangers of wave technology, decides to use this plane crash as a springboard to sell more copies.<br><br>There is no "growing speculation" at all, only a growing number of media outlets prepared to sell-out by propagating a completely unfounded story which lacks any kind of evidence.

The throttle position provide the engines with thrust commands. The only computer that can shut the engines down is the one on the engine and that is only if the computer detects the engine has a serious fault. Virtually impossible for two engines to have the same fault at the same time. The only way to shut the engine down manually or by accident is by moving the Fuel Lever to Cut Off, and you can't do that by accident. No other system can command the engines to shut down. Its fail safe.]]></description><dc:creator><![CDATA[Martin]]></dc:creator><pubDate>Jan 23rd 2008 1:54AM</pubDate></item><item><title><![CDATA[Comments on Was Wi-Fi Behind the Boeing 777 Crash In London?]]></title><link>http://www.switched.com/2008/01/22/was-wi-fi-behind-the-777-crash-in-london/</link><guid isPermaLink="true">http://www.switched.com/2008/01/22/was-wi-fi-behind-the-777-crash-in-london/</guid><description><![CDATA[WiFi, ECM, cell phone, fuel contamination, EMP....You are all going to look pretty silly (along with BA extolling their "heroes") when it comes out this is simply a case of the pilot getting behind the airplane and unable to recover in time, possibly compounded by a single engine failure.]]></description><dc:creator><![CDATA[Bill]]></dc:creator><pubDate>Jan 23rd 2008 9:22AM</pubDate></item></channel></rss>
