More than one year has passed, the Malaysia Airlines flight MH370 remains a mystery. Over the period of time, several researchers have come up with theories claiming to know what happened to the missing Boeing 777. Despite multiple continuous search efforts, the location of the plane remains unknown. Also, no traces or debris have been spotted in the search zone. However, a group of mathematicians have presented an explanation how plane crashed and why investigators could not locate any debris.

According to Huffington Post, based on their research, scientists from Texas A&M University at Qatar, Penn State, Virginia Tech, MIT and the Qatar Environment and Energy Research Institute suggest the reason why investigators could not trace the plane is because it "nosedived" or plunged vertically at or close to a 90-degree angle in the Indian Ocean. The study was led by the mathematician Goong Chen. It has been published in a journal "Notices of the American Mathematical Society."

What happened during the "final moments of MH370" will remains a mystery "until someday when its blackbox is finally recovered and decoded," Chen was quoted as saying in the press release on Science Texas A&M University's website. He insists that "forensics strongly supports" this theory.

The team of researchers used applied mathematics and computational fluid dynamics during their research. Before concluding, the group of scientists created five different scenarios to test the theory claiming that a plane could sink without any damage. They even tested a method that was used by Captain Chelsey B. "Sully" Sullenberger" to safely bring down the US Airways flight 1549 in the Hudson River in 2009.

According to the theory, the vertical entry into the water is "smoothest" causing a little or no damage to the plane. The lack of debris or oil spills from MH370 suggests that the plane crashed in to ocean vertically, according to the Mathematician and faculty member in the Department of Mathematics at Texas A&M University's main Campus at Texas.

Malaysia Airlines flight MH370 disappeared on March 8, 2014 with 239 people, of 15 different nationalities, on board. The plane vanished few minutes after its take off from Kuala Lumpur International Airport, Malaysia and never reached Beijing Capital International Airport, China. The plane is said to be crashed into the Indian Ocean. But the lack of debris and traces makes it one of the biggest mysteries in the history of Aviation.
