A Comp Air 8 has crashed in Finland, killing 7 parachutists while 3 managed to jump out of the plane. There might be still people missing.



Apparently there was an engine defect.

What was about MH370 search? It seems that people forgot of it no? Everyday lesser, I dont hear anything since many days back in the news... Now hard to find it without the black boxes pings i think...

conspiracies ... theories ... news ... breaking news ... fake news ... rumors ... every thing we had about this missing MH 370. They spent some hundred million dollars in search and are going to spend more .... even they sent Bluefin-21 robotic sub to find the black box which they say will reveal the exact reasons for the mishap ... but we had no luck as this sub also brings nothing about the missing plane ... so question is does it really crashed in sea??? if it is .... the location they are searching is really the one??? it seems govt.s are blindly pouring dollars into the search without the trust worthy info ... god bless the world ...

How can an enormous state-of-the-art 300 million $ B777 just vanish in the air like that, with no sign for nearly two months now ?

It's really funny that it still happens in an era where almost every smartphone, tablet and electronic device can be track down by GPS and telecommunications network , with a precision of less than 10 meters accuracy.

Why not just buy the underly advertised Tile lost and found GPS device for 19.95$ and stick it on the plane to track in real time on an iPhone "Find my Boeing" app where the f*** it is - instead of putting millions of dollars worth on it of useless equipment .

GPS can't track down anything. It's a one way system that has satellites that transmit signals that can be picked up by mobile devices to pinpoint an exact location. Your smart phone or any GPS receiver doesn't transmit any signal back to the satellites.

And even though most communication systems where turned off there were still some signals picked up by telecommunication satellites that brought the search to the southern part of the Indian Ocean. Which is very large and very deep, they need to find the haystack before they can find the needle.

And if it now lying on the bottom of the ocean there would be no way that any satellite would pick anything up. The pings from the black boxes could only be picked up by very sensitive special equipment. And even with that equipment they could not accurately locate the wreckage, simply because the ocean is too deep. The pressure of the water and the ocean floor will distort any signal which is send from those depths.

It's not a unrealistic assumption that we will never find this plane again.

Agreed! Even if the civilian technology fails, surely the militaries in the region should have been on top of it!

Yes, I know that, my last sentence was a joke .
Though, as I said upper, smart phones and co. uses telecommunications networking to transmit GPS positions to other devices. Planes would use satellite telecommunications to transmit their positions, as their is no land network over the oceans and in many remote areas.
Moreover, a GPS receiver + satellite transmitting device with antennas, shouldn't be bigger than a shoe box, making it relatively easy to install on any commercial aircraft.

That is why it is important that this system should be independent from any internal interferences (per ex. crew, fire, etc.). Optimistically, it may work by its own power supply (per ex. batteries with solar charging, or very long lasting). Furthermore, it look stubbing that a pilot, or any person in the cockpit can unplug black boxes, TCAS, ACARS, etc. - All being vital components.

Today, any transportation or logistic firm can track its own fleet via GPS and GSM; know in real time fuel level and consumption, speed, exact position, problems with vehicles, but also thanks to live HDD recording, follow the history of all these parameters, as per example, position 2 hours ago, last tanking, etc.
I don't see why it wouldn't be possible for passengers airplanes, and mostly, that it still isn't used in 2014 .
