The man leading the search for Malaysia Airlines Flight MH370 is showing the strain after almost two years of fruitless toil.
Martin Dolan, head of the Australian Transport Safety Bureau, said he struggles to sleep at times, gnawed by thoughts that wreckage from the Boeing Co. 777 may have slipped through the sonar net scanning 120,000 sq. kilometers (46,330 sq. miles) of the southern Indian Ocean.
MH370 is weeks away from becoming aviation's biggest unsolved mystery since Amelia Earhart disappeared in 1937. Of the 3 million components in the jet, only one has turned up — a barnacle-encrusted wing flap — on Reunion Island, thousands of kilometers from the search. There have been no traces of the 239 people on board, their luggage or even the life jackets that were supposed to float.
