Very worrying and sad !
I'm in Spain at the min and the news have reported that something strange was spotted off the Canaries earlier today - Watch this space...
My mum's in the Canaries on holiday. She hates flying at the best of times. I hope she's not paying attention to the news or she'll never come back to England.
Still, at least they're making some headway, even if there's no hope of survivors.

But they didnt plummet from the sky at 500 mph screaming for their lives.Originally Posted by kalniel
There were children on there too. Imagine how scared those people were and it is a bit gut wrenching

oh dear, i was going to go to uni to do avionics next year
our boiler broke so we has no heating or hot water, this is the bloody result ^^
Crazy story; spotted this on Wikipedia yesterday, just about to check out the times article now. First thing I thought of was Lost also, but as everyone has said the only difference is survivors are highly unlikely, unfortunately.
OMG did anyone see the Cisco advert before the video, not suitable at all!
oh dear
at that ad

Ah but how can you build a perfect enough conductor for that much power?
throw new ArgumentException (String, String, Exception)
I didn't see any ad
pretty easily from the sounds of it :s i get the feeling you could probably make your own out of coat hangers or chicken wire or something
A shopping bag lined with aluminum foil acts as a Faraday cage. It is often used by shoplifters to steal RFID tagged items.now that is interesting
Vodka
i didnt see one either , perhaps it was removed, why was it bad??I didn't see any ad
An anti-static bag is nothing more than a Faraday cage too!
Well, that's a tree, and hence not a very good example of what lightning does when it hits a plane. Trees, as a rule, aren't very conductive... and so the ohmic heating vapourises the tree's sap and the tree explodes.
Should be fairly easy, although as someone already said, you can get some truly monster lightning bolts.
Say for starters a modest bolt of a 1,000,000 Volts and 10,000 Amps, which gives a Wattage of 10,000,000,000. If the bolt lasts for 1 second, then that's 10 billion joules of energy deposited assuming all the electrical energy is converted to heat. In a decent conductor such as the aluminium skin of a plane, only a tiny fraction of that energy is going to get converted to heat. As a very conservative total guess, say the bolt loses 1/1000 of its energy passing through the plane... that gives 10,000,000 joules deposited... which is about the same energy as in 10 chocolate bars.
Apparently you can get bolts with billions of volts and ~100,000 Amps... I think at that point I'd rather not be in the plane

Debris spotted 400 miles off the coast of Brazil
(and that unfortunate advert in full: http://www.cisco.com/en/US/solutions...avel_less.html)
EDIT: Just watched the advert - dear christ that was unfortunate... but the blogs say it was played before the Hudson crash, not the Rio incident.
