mh17-partMalaysia Airlines, which had a respectable safety record before 2014, has suffered two disasters so far this year.

On March 8 Flight MH370, carrying 239 people from Kuala Lumpur to Beijing, lost contact with air traffic control and has yet to be located.

And yesterday, another  Malaysia Airlines plane traveling from Amsterdam to Kuala Lumpur crashed near the Russian border in eastern Ukraine. Malaysia Airlines confirmed that the aircraft did not make a distress call. The flight was carrying a total number of 298 people – comprising 283 passengers including three infants of various nationalities and 15 crew of Malaysian nationality.

The crash was caused by a surface-to-air missile. Ukrainian officials have blamed pro-Russia separatists who control large parts of the area; the rebels have denied any involvement.

Russian President Vladimir Putin also told Dutch Prime Minister Mark Rutte on Friday that he wanted a “thorough and unbiased” investigation. Russia also denied any involvement, saying it had not supplied separatists with a Buk missile system, which can propel missiles high into the air at great speed.

But Anton Gerashchenko, an advisor to Ukraine’s Interior Ministry, said that rebels indeed had the weapon and that it had been provided by Russia.
