Plane talking: pilot uses aircraft to write 'Hello' on radar tracking map
Private aircraft flies a route above German countryside that when tracked on radar spells out a friendly greeting

A pilot who used his plane to write “hello” in its flight path reportedly has a track record of “inventive flight art”.
Flightradar24 recorded the 37-minute flight beginning near Agathenburg, in the Niedersachsen region of Germany, on Monday afternoon.
The Robin DR400/180 Régent aircraft is registered D-EFHN and is privately owned, though the identity of its pilot is not known.
Flightradar 24 confirmed to the Guardian that the simulation showed a real flight, adding: “This aircraft has a history of inventive flight art.”

Earlier this year, it drew a portrait of an airplane, signing off with what appeared to be a signature; and, on a separate flight over northwest Germany, a heart.
Flightradar24 is a global flight tracker that provides real-time information about air traffic around the world from data from a variety of sources, including satellite and radar.
It has previously reported on “Flower Guy”, who practises patterns “that end up looking like flowers” in a private plane over Santa Clara.
In April last year, an Air Malta plane drew two hearts in the sky to mark the marriage of two of its employees.
