Looks like the crash of China Eastern Airlines #5735 a couple months back may well have been what a lot of us suspected - pilot suicide.

The China Eastern Airlines plane crash that killed 132 people is believed to have been caused by an intentional act, according to U.S. officials who spoke to ABC News.

The Boeing 737-800 passenger jet was flying from Kunming to Guangzhou on March 21 when it plunged into a mountainous area in Guangxi, China. All 123 passengers and nine crew members were killed.

The officials who spoke to ABC News point to the plane’s flaps not being engaged and landing gear not put down. The near-vertical descent of the plane, they believe, would’ve required intentional force.

Investigators also looked into one of the pilots’ personal lives and background and believe he may have been struggling through certain issues right before the crash, ABC News has learned.
