In a span of almost five months, Malaysia Airlines lost two planes, which put its reputation in jeopardy. The first incident was on March 8, 2014 while the second was on July 17, 2014. Both incidents involved Boeing 777.

Malaysia Airlines is dealing with the outcry of the families and relatives of the deceased in both incidents. There is no confirmation yet as to the real cause of the MH17 crash, although leaders of various nations had shared their speculations based on expert findings.

Before proceeding, note that there are theories collected from the Internet.

1. A Ukraine missile shot down the plane

In a report by The Sydney Morning Herald, Ukraine stated that the plane was shot down by a missile while traveling over the eastern part of the country were war raged. Russian President Vladimir Putin blamed Ukraine for the disaster, saying that Kiev should not have renewed its operations against the rebels in the eastern part of the country. Evidence was also presented that the people responsible for the attack were very much aware that it was a civilian plane. They were heard talking about the aircraft passing through the checkpoint before the missile attack.

2. Mistaken identity

In a report by Mashable.com, Charles Oman of the department of aeronautics at the Massachusetts Institute of Technology said that although it is too early to draw conclusions, terrorism can be a possible consideration. The security in Amsterdam, however, is competent. He said, "Given the military conflict in the region, one has to be concerned that identities could have been mistaken." Other experts speculated that the pilots of the plane may have also lacked experience in such circumstances and acquired minor information about the intensity of the conflict, which did not prevent it from traversing over such territory.

3. It was intentionally shot down by pro-Russian separatists

In a report by USA Today The Pentagon said that there is strong evidence that the SA-11 missile was launched by Russian-supported separatists. Vice President Joe Biden said the crash was not an accident and that it was blown out of the sky. Ukrainian Prime Minister Arseniy Yatsenyuk described the disaster as an "international crime" while President Obama described it as a "global tragedy". The surface-to-air missile, which was fired from a Buk launcher, was capable of reaching altitudes of up to 72,000 feet.
