With her colleagues, they went through all the available information and assessed the uncertainties of each piece of data, all the different reasons why the plane might have crashed, and applying Bayesian principles of probability to work out the most likely location of the plane.
matched
They took the last known location of the plane and estimated it couldn't have flown more than 40 nautical miles in any direction from that point.
matched
Keller and her colleagues gave a map to a search team, indicating the areas they thought the plane was most likely to be in.
matched
A team went to look, but they didn't find anything.
matched
That assumption was that the black box was still working, still emitting a signal that searchers could hear.
matched
Historically, that has been true nine times out of ten.
matched
So in early searches, the teams have been sweeping the areas close to the plane's last known location, listening for the ping of the black box or voice recorder.
matched
But what if the black box and voice recorder weren't sending a signal?
matched
That would totally change the probability map.

And it took two years to find Air France flight 447.

Colleen Keller is not optimistic.

I contacted Nicholas Kristof, but he wasn't able to take part in the programme.

As far as the figure concerning women was concerned, I assumed it was referring to murder.
voice-verified
But actually, I looked at his book and it refers to the phenomena of missing women.
voice-verified
I couldn't find the exact numbers he used for his comparison, but I'm assuming he's equating girls killed with missing women.
voice-verified
So what does he mean by missing women?
voice-verified
Back in the 1970s and 1980s, academics were studying high mortality rates for girls in certain countries.
voice-verified
One of those was the famous economist Amartya Sen.
voice-verified
He wrote a number of papers exploring why this might be.
voice-verified
I spoke to him on the phone and this is one of the examples he gave.
