The incidents keep coming.
A United Airlines flight from Sydney, Australia, to San Francisco, United States, was forced to turn around just two hours after takeoff on Monday.
The plane, a Boeing 777-300, was rerouted due to a "maintenance issue", the US airline said in a statement, linked to by US media.
“The plane landed safely” and there were no injuries, United Airlines said.
Firefighters and police officers were waiting on the tarmac, American media reported.
The 183 passengers and crew members were taken care of overnight, before being able to board a new flight to San Francisco the next day.
A video taken by the “plane spotter” (aviation enthusiast, Editor's note.) New York Aviation shows that a door located at the landing gear of the aircraft opens at the time of takeoff, allowing an escape liquid.
Smoke can also be seen on one of the rear tires.
Black series for United Airlines and Boeing
This is the fifth incident in a week for United Airlines.
Last Thursday, a Boeing 737-900 had to turn around in Houston minutes after takeoff after the engine caught fire mid-flight, while the same day a Boeing 777 made an emergency landing in Los Angeles after having lost the tire on one of its wheels during takeoff.
A Boeing 737-max skidded off the runway in Houston on Friday, and the flight from San Francisco to Mexico City was diverted to Los Angeles after a problem with the plane's hydraulic system, the airline said.

United Airlines is not the only company that has suffered incidents with aircraft from American manufacturer Boeing in recent months.
In early January, an Alaska Airlines 737 MAX 9 lost a cap holder in flight.
On Monday, a Boeing 787 Dreamliner operated by the Chilean company Latam between Sydney and Auckland violently lost altitude in mid-flight after a “technical incident” according to the company, injuring numerous passengers.
The American manufacturer is at the heart of several investigations after a series of incidents and production problems.
He ordered his employees to take “immediate actions” intended to strengthen the quality and safety of its operations.
