A pilot got into the festive mood by flying his plane in the shape of a Christmas tree in the skies over Germany, radar-watchers have spotted.
The captain left the port city of Hamburg and then traced the pattern, complete with lights, as he flew as far as Stutggart, about 400 miles (650km) away before returning five hours later.
There were no passengers aboard the test flight.
On Twitter, Airbus said: "Some early "Season's Greetings" from one of Flight Test Teams in Hamburg."
The shape was much more polite than a crudely drawn penis etched out in clouds by a US navy warplane.
