Not good.
Presumably they know where it went off radar?
Whilst it's possible the plane ditched safely, it's highly unlikely the passengers will survive in a choppy sea for very long
I always thought planes were protected from lightning strikes though? http://www.physlink.com/Education/AskExperts/ae568.cfm
What i want to know is why there aren't a) GPS transmitters in the black box b) GPS transmitters in the plane that are separate from the avionics systems. It would seem logical to have some sort of beacon device that automatically sends a mayday signal or similar if it decides that the plane is either ditching/crashing or has - in the worst case scenario - suffered an ignited fuel tank. A lot of private pilots carry devices similar to this - they're typically small things that you can keep in the cockpit that basically send out a message with your location, i'd be really surprised if a commercial airliner didn't have something like it or more advanced.

radar doesn't cover the ocean and yes it is protected but there is some sort of super lightening that can punch holes through planes etc

GPS then? The airspace over the Atlantic isn't exactly quiet, would make sense for ATC to monitor where people are!
Super lightning, hmm. I think more likely the bolt hit one of the wingtips and left through the tail or something to that effect, and hit the avionics on the way.

Truly terrible news
One can only imagine what it's like for the families
actually I think its called megalightning

Lightning can be amazingly distructive:

Not that much you can do to protect agianst that!
I wounder if this will help or hinder the whole ally vrs synthetic debate!

You'll probably find it'll have some sort of Sonar Locator Beacon fitted to help with finding it in the sea. However, how long it lasts, it's range and the type of equipment nearby to pick it up will determine how "easy" it will be to locate. Taking the last known position should certainly help with the search.
All airplanes including airliners have ELT beacons that are separate from the avionics and transmits their location when an impact is detected. New ELT's are 406mhz, which are satellite tracked. Basically the same as the spot devices but more powerful, automatic and use an emergency frequency rather than the SPOT's commercial one.
Transponders are designed to allow airplanes to avoid each other, rather than for finding wreckage, but new technology called ADS-B is a big improvement on the somewhat outdated system, and uses GPS for position reporting rather than relying on Secondary Radar.
Things move a bit slowly in aviation circles, mainly due to a big disconnect between Airlines, Washington and GA. Europe is still trying to implement Mode S, which offers little benefit over mode C.
Bloody Hell The Times, did you really have to drop the word terrorist in there? Some idiot's going to pick up on that and run with it. Yes let's turn a still unfolding likely tragedy into some sensationalist bollocks.
PHP Code:$s = new signature();
$s->sarcasm()->intellect()->font('Courier New')->display();
For some reason I find this story really upsetting :|
I feel nothing but sadness for the families of those involved. Let's not kid about, we're talking 228 corpses here
Yes quite right - it is a tragedy.
However, many many more people than this lose their lives every day in road accidents, yet they're hardly ever reported.
Which is why it's all the more shocking. We accept road travel as having a certain level of risk, over which generally we accept that we have some degree of control or responsibility. A plane disappearing off the map - a plane from a real company, not from Wooden Box Airlines of Zimbabwe - is something we NEVER expect to hear about. And something which is a total shock whenever we do.
sad!
