Three Apple workers hurt walking into glass walls in first month at $5bn HQ

Emergency services called to Norman Foster-designed Apple Park, which Steve Jobs called 'a shot at the best office building in the world'

Employees in Apple Park, Apple's grand new spaceship-style headquarters in California, keep walking into glass doors and windows.

Despite warnings from a building inspector that people would not be able to tell where the door ends and the wall begins, at least three Apple employees walked or ran into the ultra-transparent glass hard enough to require emergency medical treatment during the first month of occupation, according to recordings of 911 calls obtained by the San Francisco Chronicle.
