March 12 (Bloomberg) -- Bloomberg News’ Megan Hughes reports on the plane-tracking technology available on Boeing aircraft that was not used by the Malaysia Air flight that disappeared over the weekend on Bloomberg Television’s “In The Loop.”

Flight 370 missing asia.

Megan hughes joins us now with more.

Do we know why they opted out of this and what is -- what is it exactly?

Class the carrier gets a lot of the same information itself.

This is all according to a person familiar with the matter.

It would have provided a back up to the airline's on surveillance of the plane.

What we are talking about is the boeing health management program.

Polls and performance data to help airlines spot mechanical falls early.

Onboard computer data via an online link.

About 75% of boeing 777's used the system.

Again, this was a maintenance and monitoring system designed to use posts flight and not as in-flight monitoring in the case of effect -- the crash.

It could have provided valuable information on what was happening on board when radar contact was lost over the weekend.

Class we have talked so much about the search for the airplane and also for the black boxes, which gives clues as to what happened here.

How come we do not have data from the black boxes?

The data stream live so we actually have it elsewhere?

A good question and one that gets brought up free much every time there is a crash.

The air france in 2009, a big debate being the ignited all over again.

The answer is simple.

Technology is there.

What is prohibitive is the cost.

A conventional black box, like the one they're looking for, they usually cost 10,000 to 20,000. it is a longtime expense.

Compare that to the hardware needed to transmit the data.

$57,000 per plane according to the new york times.

The base cost, on its face, more expensive but manageable.

The real expense comes when you look at the volume of data we are talking about.

Black boxes contain 25 hours of information along with two hours of cockpit audio.

One analysts estimated a terabyte of data.

A tremendous amount of data, the cost to send it via a satellite, three-five dollars per minute.

We're talking about hundreds of millions of dollars a year.

Very extensive.

Bottom line, regulators have not required it's airlines have not in the money.

Chris really interesting.

Thank you for bringing it for us.
