NASA’s 747SP, the Stratospheric Observatory for Infrared Astronomy, abbreviated SOFIA, has crossed the Atlantic on her way to Lufthansa Technik in Hamburg. The one-of-a-kind aircraft will be touching down shortly after 19:00 local time this evening to undergo a C-check with the German maintenance specialist.
On her way for a C-check
The modified jetliner, which carries a 106-inch diameter telescope, is currently on her way from California, USA, to Hamburg, Germany. A spokesperson for Lufthansa Technik told Simple Flying that the aircraft is to run through a C-check with the maintenance provider. In addition, some of the scientific equipment is to undergo technical servicing. A C-check usually takes an aircraft out of use for one to two weeks.
This is not the first time SOFIA has made a call at Lufthansa Technik’s headquarters. SOFIA made the journey to the hangars in Hamburg for a complete overhaul in 2014. She then came back in 2017 for a scheduled heavy maintenance check.
