Switzerlandâs reputation for clockwork precision is facing a brutal reality check as a dual crisis strikes the heart of national aviation.

As technical glitches at Skyguide collide with a global energy squeeze, the Swiss aviation sector finds itself in a defensive crouch, battling to maintain safety and schedule in an increasingly volatile environment.
