Based on the most recent analysis of satellite data, the plane is believed to have ended its journey in seas far west of the Australian city of Perth.
The latest zone is some 1,000km south west of the area which was extensively searched with underwater surveying equipment in April.
Over the last few months, the Australian authorities have been conducting an underwater depth survey of the latest search area.

Airbus 320 has a best rate of glide speed of 130 knots (150 mph). Capt. Sully Sullenberger recalled “having the Green Dot” meaning he thought he had 130k, actually he was about 15k below that (115kts,FDR did not record beyond that #)
The impact with the water had ripped open a hole in the underside of the airplane and twisted the fuselage, causing cargo doors to pop open and filling the plane with water from the rear.
From the NTSB report :
The investigation determined that the airplane
s descent rate at the time it impacted the
water was 12.5 fps, more than three times the descent rate of 3.5 fps assumed during ditching certification, resulting in external pressures on the aft fuselage,primarily from FR55 to FR70,which significantly exceeded the values
established to demonstrate compliance with the
certification criteria. These external pressures were sufficient to cause the large-scale collapse and failure of the aft fuselage frames, cargo floor, and passenger floor struts and to initiate cracking of the lower fuselage skin, allowing water to enter the airplane. Further, the water
ingress and continued forward motion of the airplane through the water resulted in postimpact pressures and suction forces that caused additional damage, including the failure of the lower fuselage skin panel and aft pressure bulkhead.
Therefore, the NTSB concludes that the airframe damage was caused by the high-energy impact at the aft fuselage and the ensuing forward motion of the airplane through the water.
Look at the pictures of the aircraft after it was recovered lots of holes, BTW when the Cargo doors came open, baggage was everywhere, some were recovered weeks after.
I always thought Sanguine meant "mellow".
I am very familiar w/ Scott Peterson.
He was tried in the Courthouse in Redwood City, which is where my original Birth Certificate resides.
I guess capital crime was a vehicle with which to increase your vocabulary, and I can't fault that!
Most often “sanguine” means “cheerfully optimistic.”
Or, sometimes, having a healthy reddish color.
You have to understand, there are many huge areas around the globe, mainly over the oceans, that are not covered by radar. In fact I would submit that once a plane more than a 400 or 500 miles from a coastline over the open ocean they will be out of radar contact due to radar ranges and the curvature of the earth until they fly close enough to another radar site. You can fly over the Indian and Pacific Oceans and at time have to fly 1000 or maybe even 1500 miles while outside of radar coverage. Fly from Sydney Aus. to say Johannesburg SAfrica and you’re going to fly for hours at some point outside of any radar coverage, with the exception of navel ships that are out to sea and happen to be close enough to your path. Also, Radar, even today is far from perfect, there are times when atmospheric conditions can make it difficult to detect contacts that are technically within range but relatively far away. Air traffic radars are not nearly as advanced as the military radars like the AEGIS phased array type. Air traffic radars are the old fashioned spinning antenna type, they are to be honest, old fashioned and past their prime to say the least.
