Apple's new state-of-the-art, $5 billion “spaceship” campus boasts a huge glass-walled building with the latest in energy efficiencies, and a 100,000-square-foot fitness center, and sits amid an orchard, meadows and a pond. But the serene office space appears to have caused some trouble for several employees.

According to transcripts obtained by the San Francisco Chronicle, at least three 911 calls were made from Apple Park after people walked into the building's signature glass walls. Two of the emergency calls happened on the same day in January — not too long after employees started moving into the building — and the third occurred just 48 hours later.
