Malaysia Airlines MH370: Why airlines don't live-stream black box data:

Here's a news item on this, much-discussed-on-here subject:

It occurs to me that the pilot's unions may not be too keen of continuous surveillance on them but that is what the cockpit flight recorder already does, anyway.

Nah.

Hmm.

Malaysia Airlines Flight MH370: 'pulse signal' reportedly detected by Chinese ship in search zone.

Quick! Everybody buy a lottery ticket!

The chances of finding that are thus (unless they've known all along where to look):

[andyt]

The ping was only for 90 seconds, while the beacon would be transmitting continuously. Possibly they were far away from it and moving too fast, but they should have been able to turn back and find it again. Also, this is the frequency used for all sorts of locators, and could have come from a civilian or military equipment that was lost overboard. Also, if it's the voice recorder, it would only have the last couple of hours of the flight on it - wouldn't tell why the plane turned around in the first place

[Jabberwalker]

If it pinged for a year, they may still have long odds on finding it. due to the rather vague (and potentially huge) search area that they are dealing with.

[andyt]

Well, no. The signal will only go a distance of 20,000 feet and it's 15,000 feet underwater, so the circle where it would be picked up would be by pythagoras the radius of the circle would be 13,000 feet, so the area would be about 19 square miles

No, actually, the area that it could be located in is about the size of Europe. If they lucked into coming within 19 miles of it (a chance event at best) then yes, they will probably find .

[andyt]

I'm talking about the signal they picked up - if that does turn out to be the plane, it would reduce the search area to a very small one indeed.

[Jabberwalker]

They picked up a lonely little "ping" and if it comes from that aircraft, with that 19 mile audible radius, the Chinese MUST have known where to look (possibly implicating them) OR an astronomically improbable thing has just happened.

Thinking the Chinese had something to do with the plane going down?

... only now that they have magically come up with a "PING" that is audible for only 19 miles while patrolling an area the size of China at ten or fifteen knots. Does that smell right to you?

Let the wild speculations...BEGIN!!!!

Well, either it is an astounding coincidence that a Chinese ship "just happened" to hit a target at an unknown position, or they didn't actually hear a ping, or, they have some highly developed listening capability that covers the most unlikely parts of the World's oceans. It has to be one of the three.

The British now have one of their Subs there and I'm sure the others do too. The worlds best commercial locating equipment may be nothing compared to the classified Military equipment. If this is in fact a "hit" this soon out, it may have been guided there by that source and we will never hear about that.
It's a positive sign but unless they get another hit on the next pass, they will just keep mowing the lawn. They are also towing a few miles of cable so they won't just stop and start doing circles. There is also no directional locating technology with these devices. They will need multiple hits from different locations to triangulate its location.
