    Any idea how often they disappear from a screen? It can happen all the time for any number of reasons, more often than not, however, they simply pop up again later on.

    The RAF's Quick Reaction Alert aircraft are often launched because military radar has picked up something that has eluded civilian ATC because of issues with transponders - the two systems work differently.

    The only thing that's unusual is the fact that these two have then gone on to crash. In the case of this most recent one, heavy storms, especially electrical, is easily enough to interrupt a transponder signal and prevent that from getting in/out of the aircraft, with the storm itself then being enough to down the aircraft.



    What you have to understand is the difference between the systems. Civilian Air Traffic Control is not a radar in the conventional sense. It doesn't "see" the aircraft; it's not a signal that's sent up, bounces off the metal work, and then back to the radar station. It's purely radio-based on the signal coming off the aircraft's transponder. The Civilian ATC can only see you if you're sending out that signal. You can only get BBC1 on your tv if BBC1 is working. That's the case here. For whatever reason, and in this most recent case it's clearly the reported storms, the signal was interrupted, so the flight is then 'missing'. Normally, they'd just pop up again on the other side of the storm. You have no idea how common that is.

    They're probably all dead. I mean, it went missing over 12 hours ago and the flight can't be more than five hours so there's no way it can be in the air and there's no way it can land without ground assistance and there's no way it can get ground assistance without it not reaching the media.

    Come on mate. That's not really breaking news. We knew the plane had crashed ages ago.

    'Thought' we knew it crashed ages ago, just confirming it.

    You know some believe the Titanic was victim of a terrorist attack? it's connected with the federal reserve. One of the men who died on the Titanic was Isidor Straus a wealthy Jewish-German who many believe opposed the Federal Reserve. You could say he was an anti-Zionist. There were a number of wealthy rich people who at the last minute decided not go to onto the Titanic.
