"In 1990, a panel of the windscreen on British Airways Flight 5390 fell out at 17k feet, causing the cockpit to decompress & its captain to be sucked halfway out of the aircraft. The crew held onto him for more than 20 minutes as the copilot made an emergency landing. The pilot made a full recovery.""If I remember correctly, the accident happened because someone eyeballed the screws when they replaced the window, and they were like a millimeter off."Pretty close. The screws used to secure the windshield were different lengths for different areas. Instead of using a template to know where each screw came out of or referring to the IPC (illustrated parts catalog) they just put the screws in a pile and slammed them back in without ever knowing if the screws were actually grabbing enough threads on the nutplates."
