A KLM Boeing 737-900, registration PH-BXS performing flight KL-1574 from Athens (Greece) to Amsterdam (Netherlands), was enroute at FL400 about 90nm southsoutheast of Prague (Czech Republic), still in Austrian Airspace about to enter Czech Airspace, when the crew donned their oxygen masks, declared PAN and initiated an emergency descent to FL100 reporting they had a problem with a cockpit window. Upon check in with Prague Center, in the descent, the crew requested to divert to Prague. ATC inquired whether after landing the crew would be able to taxi, the crew advised the problem was under control, they had contact to the outside and were completely in the clear. After levelling off at FL100 the crew cancelled the PAN and removed oxygen masks. The aircraft landed safely on Prague's runway 24 about 25 minutes after leaving FL400 and taxied to the apron.

Passengers reported that the first officer's window had cracked developing a "spider web" all over the window.

The airline confirmed a technical issue, a broken cockpit window.
