One of those beautiful winter mornings at Nytua with a good number of "The Phantom Mother Squadron" / 301 Hoktai Phantoms going out for their first sortie of the day
with a small device sticking out behind the nose gear this WTD61 Transall is test-flying the "ISISS" (Integrated SIGINT Sensor System) [maybe an abbreviation you wouldn't use nowadays...]
"Offener Himmel", Germany's Open Skies aircraft. After the tragic loss of the Luftwaffe's Tu-154M in 1997 and a resulting 23 year long break without having an own Open Skies asset, this A319 finally fills this gap.
