Plane crash in Iran raises questions about terrorism and missile attack

The crash of the Boeing 737-800 from Ukraine International Airlines at Tehran International Airport on Wednesday 8 raises chances ranging from mechanical failure to terrorist action, passed through the theses of collision and anti-aircraft missile attack fired by mistake by the Iranian Army. The case not yet elucidated by the Iranian authorities results in pressure from Ukraine, Canada and the United States over Tehran at a time of fragile truce between Washington and the Ayatollah regimes.

The plane crashed shortly after the start of the Iranian attack on bases housing U.S. troops in Iraq on Wednesday. All passengers and crew died: 82 Iranians, 63 Canadians, eleven Ukrainians, ten Swedes, four Afghans, three Britons and three Germans. Iran's measured information about its investigations, including the contents of the black box, feeds theories about the tragedy.

The head of Ukraine'sNational Security Council, Oleksiy Danilov, said in a post on his Facebook account that the main chances for the ps752 flight crash revolve around: terrorism, collision with another flying object (such as a drone), a technical failure that would have generated the explosion of engines and an anti-aircraft missile attack against the aircraft. All theories converge at an unusual point: when it fell, boeing was already on fire,as the Initial Iranian government report attested.

Shortly after the accident, videos posted on social media showed a bright spot falling into the sky and then an explosion.

Security sources from the United States, Europe and Canada, who asked not to be identified, said the initial assessment of Western intelligence agencies is that the plane suffered a technical malfunction and was not shot down by a missile. There was evidence that one of the jet's engines overheated, according to a Canadian source.

Tehran's position coincides with that of western countries. Iran claims to have been a mechanical failure in the aircraft and denies that the Army fired a missile by mistake. As for the black box, The head of the Iranian Civil Aviation area, Ali Abedzadeh, said he will not send the flight details to Boeing or the United States. Under international law, Iran has a responsibility to investigate the fall.

Alongside Ukrainian experts, experts from the UK and Sweden will join the Tehran investigations.

The accident comes at a difficult time for aircraft manufacturer Boeing, which collected its 737 MAX fleet after two accidents. The 737-800 is one of the most used models in the world, has a good security history and does not use the software tool implicated in the 737 MAX falls.

"We are in contact with our airline customers and support them at this difficult time. We are ready to help in any way that is necessary," the manufacturer said in a statement released wednesday. The company declined to comment further.
