On 26 January 2009, the new research aircraft HALO (High Altitude and Long Range Research Aircraft) took off on a two-hour flight in order to receive its German airworthiness certification. During the flight, all of the devices on board were checked once again. The previous flagship of DLR's research fleet in Oberpfaffenhofen, the Falcon, rendezvoused with HALO high above the Zugspitze to welcome it as a member of DLR's research fleet.
The aeroplane, a Gulfstream G550, had previously been converted from a business jet to a modern climate and atmospheric research aircraft.
