They are trying to determine whether Mr. Walters, 67, lost control or if some mechanical failure caused the bus to go off the road.
A mechanical failure caused the crash, according to the officials, but a Taliban commander south of Peshawar, Tariq Afridi, told local journalists that the Taliban shot down the aircraft.
The significance of cement sheath centralisation and elevated risk of cement mechanical failure caused by wellbore operations in anisotropic fields with soft rocks formation were highlighted.
In addition, a NASA/ESA panel investigating the transient loss of the probe released a report at the press conference confirming that human error, not mechanical failure, caused the spacecraft's problems.
But in April, a mechanical failure caused an 84-gallon oil spill northeast of Tulare, a tiny town in South Dakota.

Although the P-51 was restored, mechanical failure caused a crash and the death of the pilot, a retired U.S. Navy commander; the Tuskegee Airmen endorsed and encouraged the aircraft's second restoration, and the newly restored P-51C made its debut at AirVenture 2009 in Oshkosh, Wisconsin.
However, such a packed bed design is prone to mechanical failures caused by the punctiform contacts, especially during thermo-cyclic operation.
