That 767 used on this route was showing its age and in need of maintenance when I flew it a couple of weeks ago. The video screen in the front Hospitality cabin was horribly out of focus, but lots of overhead lights and headphone jacks were not functioning. Maybe it finally got pulled off the line for a fix-up. Maybe AvionicsGuy can tell us more about this particular aircraft. Sounds like the same weather I had in MUC on the first weekend of Feb.
