Australians picked up two different signals on two different frequencies consistent with what the black boxes transmit. They got stronger, then weaker as expected with movement of the ship. One signal lasted two hours and twenty minutes. Other lasted 13 minutes. They are going back to attempt to triangulate.

Latest news this morning says the black box may be in almost 3 mile deep water.
If it I the one, is there any problems trying to recover the box that is so deep ?
Kinda sounds like someone knew exactly where they wanted to ditch the plane, and make it very, very tough to recover.

i guess if you want the issue clouded in mystery.. then picking the worst recovery zone in fuel range is a smart idea. and if the pilot did a good 'soft landing' then the debis will be minimal.. and when this much time pases.. well... we'll see.

If you're thinking that way, they would have flown it out farther from Australia than where the pingers are allegedly being heard from today. There are deeper, more remote areas within reach than where they are looking today.
Just a reminder, please keep the conversation non-political in this thread, otherwise we'll have to move it to the politics forum. :thumbsup:

The report from the Aussies is interesting. The Chinese "heard" something 600-700K away to the SSW. The Aussie equipment has to be within about TWO miles to pick up the pings. :shocked: The Aussie location looks like it is within the first southern path based on the Satellite data. The water depth in that area is just a bit deeper than the Air France crash depth. One of the search devices can just make the depth in that area. Barely. 
Pilot Charts are historical, monthly, data for wind direction, wind speed, wind direction percentages, current direction, current spend, wind calm percentages, water temperature, air temperature, etc, laid out on a chart. The Pilot Charts does not give one 100% predictions about weather in a given area but it is a good clue.
The area off of Australia where the pings might have been heard, and where the satellite pings traced the planes path, has interesting wind and current in March. The current is going counter clockwise at 1/2 knot. The current is moving AWAY from Australia and heads out into the Indian Ocean. It is possible debris would eventually spin back to Australia but it could also spin to the north and end up somewhere along the eastern, western, or northern Indian Ocean. In other words, debris is almost certainly heading away from Australia and could end up anywhere in the Indian Ocean coastline.
IF the plane crashed much closer to Australia, there is a current that flows along the coast but the plane would have had to be really close, roughly 200-300 miles. Even then, the wind is blowing most of the time away from Australia. There is ONE place were the current and wind has a chance to blow/flow debris towards Australia but the plane would have had to have crashed much closer than the data suggests. Even then the odds are not favorable for debris to wash ashore.
The wind in this area is mostly from the SSE and flows most of the time with the current. Meaning the wind is blowing away from Australia. In one area, 88% of the time the wind is from the S or SSE at Force 4 which is around 15 MPH and the waves are 3-6 feet which is not that bad. Historically, the wind blows ALL of the time. There are NO reported calm periods. Another wind rose might be where the search is taking place and the conditions are about the same with 65% of the wind from SSE at Force 4 but maybe 15% of the wind at Force 5 from the E. Force 5 is 25ish MPH and has 6-9 foot waves.
From a wind, wave, current perspective, the plane crashed in one of the worst places in the Indian Ocean if you want to find the plane. The only way the location would be worse was if the plane was farther from land to make air searches more difficult.
Looking at shipping lanes, this is a really cool map/chart I saw recently, File:Shipping routes red black.png - Wikipedia, the free encyclopedia, it looks like the plane just happened to head too, and crash in, an area with very little shipping traffic. Hmmmmm....
If there was no satellite location data, it would be almost impossible to find the plane. The plane would have just disappeared.

Every county with nuclear subs has been cruising Australia's west cost since the "south arc was suspected. Great opportunity for a military training exercise. And to snoop around everybody else's subs in the area to test their capabilities.
If the Chinese did find a pinger. It was via a sub and the location was transmitted to the surface ship with the toy hydrophone for a good show.
