Lufthansa passengers excited about solar eclipse. On March 20, customers on board LH 435 from Chicago to Munich had the rare opportunity to experience a total eclipse of the sun on board a scheduled flight. Thanks to a minor change in its flight path, the aircraft passed the complete shadow southeast of Iceland at a cruising altitude of 12,600 meters above sea level. The passengers got to see this natural event from a special viewpoint from 10.37 a.m. CET for almost four minutes – one minute longer than it was visible on the ground
