Authorities have cleared an Air Berlin pilot who aborted his final landing at the last moment to make a low pass around a control tower.
The German federal agency responsible for air safety concluded that the maneuver in Dusseldorf in October did not break rules.
Airbus A330 from Miami had more than 200 people on board, swooped around the tower before landing safely.
Control tower staff got shocked as the plane flies past.
At the time, the pilots of the aircraft were suspended by Air Berlin following the incident.
“In aviation, safety always comes first. We are taking the incident very seriously,” an Air Berlin spokesman said.
Air berlin pilot stated : “We wanted to make a mark, a dignified and emotional goodbye”
Air Berlin ceased to operate in October and parts of the company have been sold off to rival carriers.
The airline will fly its final short-haul flights under the Air Berlin brand at the end of this month.
