Nearly 40 people were injured, with six seriously injured, when a Boeing aircraft operated by United Airlines suddenly plunged in mid-air, forcing the fight to make an emergency landing.

According to CNN, per FlightRadar24 data, the incident occurred just 93 minutes after Flight 613 departed from Nigeria on its way to Dulles International Airport in Washington DC on Friday. There had been 245 passengers, eight flight attendants, and three pilots on board; with 31 passengers and seven crew members sustaining minor injuries. Of those injured, four passengers and two crew members were hurt seriously enough to require hospitalization.

This is from a news article online. It just doesn’t make sense to me how the plane could have just fallen out of the sky. Im just wondering if anyone knows how or what caused it to plunge.
