How far would those rafts drifted after a week in the water? The plane could have crashed hundreds of miles from where those objects were spotted.

Exactly, so a carrier would have made more sense.

How fast is an aircraft carrier? 30 knots perhaps, that's 35 mph.
2500 miles is three full days at top speed, assuming there was one in Perth, ready to leave at a moment's notice. So it would still have a days travel yet before it even started searching.

Edit: got my units wrong, it's 2500km, so two days journey time, so it would now be arriving. Meaning the search would have started two days later.

Well, I think the Chinese now own a carrier or two and they have the greatest stake in finding out what happened. I did read that some ships of the Chinese navy have been deployed. A carrier is a very expensive ship to operate and the oceans of that part of the world are vast. The fastest carriers are capable of around 45kts. sustained speed so that's about 1100 nautical miles a day. So, until a target was spotted, sending a carrier to just wander about in the vast ocean wasn't practical. Plus up until two days ago everyone was speculating that the plane made it to Pakistan or some other middle eastern destination.

Also, are the carriers equipped with the right sort of planes? I don't think they can just use jet fighters to search for wreckage.

Naval awacs spring to mind. No carrier operates without one.

Yeah, but aren't they radar planes? Can you use those to search the sea for wreckage?

EDIT: nevermind, they can :)

Plus most carriers have a contingent of helicopters on board. They also do not travel alone. A US carrier never goes anywhere without it's battlegroup consisting of several cruisers, destroyers, auxiliaries and submarines.

I'm sorry, but we don't have any carriers.

HMAS Success should be pretty close to the area now (if not already) and that does have a Sea King helicopter.

Also a couple of ice breakers with helicopters should be fairly close to the area as well now, but you have to remember that this area would have to 1 of the most isolated areas in the world and because it's in the area of the "Roaring 40's" it's not a very calm area either.

Today and maybe part of tomorrow, weather conditions should be fairly good, but that will deteriorate again making the search very difficult.

We also have electronic buoys in the ocean now tracking drift rates, but the actual crash site could be several hundred nautical miles further east from the original satellite picture were taken (and that's if this debris is from MH370).

Cheers.

Revealed: the final 54 minutes of communication from MH370

The entire 54 minutes of cockpit communication aboard the missing Malaysia Airlines flight can be revealed, from its taxi on the runway to its final message at 1.07am of 'all right, good night'

If this wreckage is confirmed, then where it is could have been expected, at the end of the "southern arc" given maximum flight time.


Chris, those arcs we see on the various news web sites are the possible locations of the aircraft at the time of the last ACARS transmission. They are not flight paths. Because ACARS is not designed to locate a transmitter, that is the best they can do with the data they have. Pick any point on either of those two arcs, draw a circle of about 2,000 miles radius centred on that point, and those are the possible locations of the aircraft when it ran out of fuel (assuming it flew that long). This is a very big area.

Yes, they are just an arc from the limits of the only satellite that picked up those signals. If an 2nd satellite had picked up those same signals a better area would've been determined (a 3rd would've damn near pinpointed it).

Just revealed is that the flight was carrying lithium-ion batteries and may have been the cause of the crash.

http://www.news.com.au/travel/travel-updates/search-for-missing-malaysia-airlines-flight-mh370-resumes-in-southern-indian-ocean-southwest-of-perth/story-fnizu68q-1226861867123

MALAYSIA Airlines CEO Ahmad Jauhari Yahya has confirmed MH370 had been carrying lithium-ion batteries in its cargo hold.

These batteries have spontaneously exploded on other flights, but Ahmad Jauhari dismissed suggestions that they might have been the source of a fire that caused the plane to crash.

“These are not regarded as dangerous goods ... and were packed as recommended by the International Civil Aviation Organisation,” he said.


Personally I find that if this was the case then the plane would've been found much sooner and closer to its home.

Cheers.

Anybody consider the possibility that the plane was safely landed in a terrorist attempt to use it later as a weapon?

It would be rather easy to toss a couple of life rafts into the ocean and hope that some would expend all their efforts searching there.
In the deepest waters available.

Only about 15 days of pings left, I think.

This is NOT a joke or a jest, but a most serious chance, kids.
Of course that would mean the all on board are possibly deceased now.
Terrorists have no use for live people.

I do hope I am wrong on this one.

I don't think that would be easy much less possible on a flying 777.

Who said it was still flying?
I suspect it may have landed in a foreign country. Under the radar, so to speak.
