The co-pilot aboard Malaysia Airlines Flight 370 reportedly attempted a call from a mobile phone just before the plane disappeared.

Co-pilot Fariq Abdul Hamid's phone briefly connected to a cell tower, according to reports, but was disconnected before the call was able to go through. The news was first reported by the New Straits Times, an English-language Malaysian newspaper.

The report cited anonymous sources who claim the call was most likely disconnected because the plane was flying away from the tower. The plane flew as low as 5,000 feet at points before its disappearance, which was low enough to connect with a cell tower at 7,000 feet, according to New Straits Times.

It is still unclear who the co-pilot was attempting to call, and the update is yet another mysterious detail surrounding the disappearance of flight MH370. The flight, which was carrying 239 people, including both passengers and crew, disappeared in the early morning hours on March 8 en route from Malaysia to Beijing.

Numerous theories surrounding the plane's disappearance remain possible, and investigators are still working to determine whether foul play was involved by passengers or crew members. Identifying who Fariq was attempting to reach may serve as a valuable piece of information in solving the mystery.
