The French navy has located the immediate area around the flight recorders from Air France flight AF447 which crashed in the Atlantic last year. They are now within a 3 nautical mile area of the black boxes, which is 200 nautical miles north-west of the Brazilian archipelago of Sao Pedro and Sao Paulo.
However retrieving the Air France Airbus black boxes from the ocean floor might be near impossible.
The cause of the crash remains unknown but the aircrafts airspeed had given false readings, but officials believe other factors must also have contributed including blocked pitot probes or rudder failure similar to a crash in New York in November 2001.
Finding the black boxes from AF 447 will reveal flight data and cockpit conversations, allowing investigators to build a computer model of the final moments of the flight.
A French navy spokesman said: ‘It’s like trying to find a shoe-box in an area the size of Paris, at a depth of almost 10,000 feet and in a terrain as rugged as the Alps.’ and this search for AF447 is apparently ‘one of the most complex undersea operations ever’.
It will be interesting to see if any black boxes are found almost 1 year after the disaster.
It is a very sad event but something strange but very sudden must have happened on board Flight 447.
Flight 447 left Rio de Janeiro carrying 228 people, en route to Paris, but about 4 hours after take off an automated alert was sent to Air France HQ from the plane. Initially this was reporting an electrical issue, perhaps a short circuit but there are rumours of a second alert to do with pressure in the cabin, which could be true if there was an explosive decompression (nothing to do with bomb explosions) but when the pressurised air quickly escapes from the plane. There was no further contact. Was it lightning, a bomb, or did turbulance rip off the rudder?
The plane is reported to have come down 360 miles northeast of Natal, Brazil.
The plane was in an area of thunderstorms, however, I find it difficult to believe that lightning could take down such a large, complex and sophisticated Airbus – afterall, the plane that landed on the Hudson was an Airbus. There are between 1 and 3 reported lightning strikes each year yet the last recorded crash from a lightning strike was way back in 1967 when the fuel tank exploded.
I think perhaps more likely is that lightning struck the plane and interrupted the computers and electrical systems. The Airbus is constructed so that the aircraft and also data communication associated with the fly by wire system is protected against overvoltages the indirect effects of lightning.
An overload could have caused anything to occur e.g. the wrong signals sent to the rudder might have caused a rudder hardover flipping the aircraft about and at that speed the plane would have been destroyed or the rudder ripped off due to the speed and turbulence.
It is possible, especially in an era of hightened terrorism. However with increased airport security is this as likely was it was during the era of Air India or even Locherbie. Why time it for when it is over the sea if you are a bomber – surely they would schedule detonation for a more populated area to bring attention to their ’cause’. The reason I don’t think it was a bomb is that the debris field is so small – a bomb at that height would cause a huge debris field easily seen by spotter planes.
This would also rule out a fuel tank explosion as happened to TWA-800. However, that crash was caused by a short circuit when increased current was sent from systems to the fuel tank control system, which eventually caused a spark igniting the fuel.
The only reason I can think of (these are only my observations and thoughts on what could have happened based on past cases and facts which we have to hand at present) for very little debris being found is that the aircraft hit the water 90% intact. Why 90% – the tail may have been ripped off by the turbulence. Wake turbulence caused the crash of American Airways 587 in 2001, when it encountered wake turbulence, the pilot applied incorrect pressure to the rudder which was too much and the rudder ripped off – 268 people died. Without the rudder a plane cannot under any circumstances or any pilot skill, be controlled. In the case of Flight 447 , this would explain (a) the pressure warning from the plane ; (b) possibly the electrical warnng ; and (c) The lack of further contact and limited debris field.
We won’t know until the Black Box – CVR and FDR (Cockpit Voice Recorder and Flight Data Recorder) are recovered. This will be an absolutely mammoth task as the plane is possibly thousands of feet below the surface. The Black Boxes have a battery life of about 30 days after which the pinging devide will cease. Also the longer they are in the water the more potential for damage there is. We will have to wait and see what happens and see if a cause can be deduced from this terrible accident.
There are lots of reports circulating the web at the moment, some stating that the location beacons have not been triggered, others claiming that this is a new bermuda triangle – this I believe is hype. Something happened, something catastrophic as there was no Mayday – that we do know.
Some of the headlines in the news are frightening to holiday makers who are worried about getting on board a flight. If it was me, I would have no problem boarding an A330. The airbus is a great aircraft.
Lets wait and see and leave these people rest in peace without writing silly stories about (some of these are in the tabloids) bermuda triangles, black holes, UFOs and others targetting certain aircraft with being unsafe.
