Bayes’ Theorem helped researchers locate Air France Flight 447’s black box in 2011

Days after a Malaysian airliner with 239 people aboard went missing en route to Beijing, searchers are still struggling to find any confirmed sign of the plane. Authorities have acknowledged that they didn’t even know what direction it was heading when it disappeared.

As frustrations mount over the failures of the latest technology in the hunt for Malaysia Airlines Flight MH370, some scientists say an 18th-century mathematical equation – used in a previous search for an Air France jetliner’s black box recorder – could help pinpoint the location of the Malaysian plane.

Indonesian Air Force officers examine a map of the Malacca Strait during a briefing following a search operation for the missing Malaysia Airlines Boeing 777, at Suwondo air base in North Sumatra, Indonesia, on Wednesday.

In 2009, Air France Flight 447 en route to Paris from Rio de Janeiro vanished over the Atlantic Ocean, triggering the most expensive and exhaustive search effort ever conducted for a plane. After two years, officials could only narrow the location of the plane’s black box down to an area the size of Switzerland.

But Flight 447’s black box was found in just five days after authorities contacted scientific consultants who applied a centuries-old equation called Bayes’ Theorem.

Mathematically, Bayes’ theorem gives the relationship between the probabilities of *A* and *B*, *P*(*A*) and *P*(*B*), and the conditional probabilities of *A* given *B* and *B* given *A*, *P*(*A*|*B*) and *P*(*B*|*A*). In its most common form, it is: (Wikipedia)

The proof of Bayes’ theorem is actually relatively simple, the only requirement is to know the formula for conditional probability (Learnt in H1/H2 Maths):

From this, we have

Similarly,

But since , we have . Dividing throughout by gives Bayes’ Formula:

Sincerely wishing that the MH370 plane will be found soon, and hopefully the passengers are still alive.

It has been used several times to find lost sea vessels, for example the USS *Scorpion*. It also played a key role in the recovery of the flight recorders in the Air France Flight 447 disaster of 2009.)

“We extend our deepest condolences to the loved ones of those on board Malaysia Airlines Flight MH370,” U.S. State Department spokeswoman Jen Psaki said. “Officials from the U.S. Embassies in Kuala Lumpur and Beijing are in contact with the individuals’ families. Out of respect for them, we are not providing additional information at this time.”

Among them is Philip Wood, who graduated from Oklahoma Christian University in 1985 according to school spokeswoman Risa Forrester. He earned a bachelor of science degree, concentrating in math and computer science, and belonged to the Delta Gamma Sigma service organization, Forrester said.

On Oklahoma Christian’s Facebook page, one woman lamented the “heartbreaking news” while a man remembered Wood as “gentle, kind, had great taste in music and was a wonderful artist.”

“Philip Wood was a man of God, a man of honor and integrity. His word was gold,” his family said in a statement. “Incredibly generous, creative and intelligent, Phil cared about people, his family, and above all, Christ.

Malaysia Airlines is asking for prayers from around the world for Flight 370.
