A report on Malaysian Airlines MH17 air disaster in Ukraine last year by a group of old-hand aviation security experts maintains that the Boeing might have been downed by an Israeli Python air-to-air missile.

The report was leaked via the private LiveJournal account of Albert Naryshkin (aka albert_lex) late on Tuesday and has already been widely discussed by social media communities in Russia.

The authors of the investigative report have calculated the possible detonation initiation point of the missile that hit the passenger aircraft and approximate number and weight of strike elements, which in turn designated the type and presumed manufacturer of the weapon.

 The BBC has announced the release of a documentary on the crash of Malaysian airlines MH17, which will be broadcast on May 3″:

“On 17 July 2014, Malaysia Airlines flight MH17, travelling from Amsterdam to Kuala Lumpur, crashed, killing 298 passengers in the worst air disaster for two decades.

Alarmingly, the devastating crash occurred just four months after the mysterious disappearance of Malaysian Airlines flight MH370. Is this just a coincidence? The cause of the crash has been focus of a host of conspiracy theories, many of which involve Russia, Ukraine and the CIA.

DUTCH prosecutors say the body of an Australian who perished on Malaysia Airlines Flight MH17 was found wearing an oxygen mask, raising questions about how much those on board knew about their fate when the plane plunged out of the sky above eastern Ukraine.

Prosecution spokesman Wim de Bruin says the passenger did not have the mask on his face, but its elastic strap was around his neck.

De Bruin says it is not known “how or when the mask got around the victim’s neck”.
