One thing to note is, that the maintenance of those jets is actually outsourced to Lufthansa and not done by the military. Lufthansa maintenance in SXF was doing work on that Global Express, but having enjoyed the service level of that particular outfit with a previous employer i am not surprised. On the short sector from SXF to TXL after a C-check we had more than 50 write ups (it helped that we had one of our engineers on board who helped with that stuff, we pilots focused on returning to earth in one piece), however, no ground contact of the wings on landing and therefore nothing in the news.
