An Angola Airlines Boeing 777-300ER rolling away from its parked location, into a grassy area at Porto Airport (OPO) in Portugal.
According to Jornal de Notícias, the Boeing 777 (reg. D2-TEH) arrived in Porto as DT654 at 5:43 a.m. local time after making its way from Luanda (LAD) in Angola.
The plane was parked it in the cargo area of the airport as it would not be making the return flight until 10 p.m. The Portuguese newspaper reports that around 9 a.m. local time, the aircraft started to roll free on its own accord.
The aircraft slowly rolled down the taxiway and veered off into one of the grassy areas. The 777’s right wing also came into contact with a light pole and knocked it down before coming to a stop just a second later.
Airport sources told that “someone forgot to chock the wheels of the plane, which caused it to slip into a landing zone.”
At the time of the incident, there were no crew members or ground officials on board the aircraft.
