Hopefully the problem has been correctly isolated, and it's something Boeing can take care of. I don't think any passenger jet would take to kindly to losing its windshield.
Nope, thankfully, you can't turn the aural warning off for a fire, which is what started the whole emergency process. IMO the crew was well trained because they immediately descended to 10,000 feet and returned for an emergency landing.
Does anyone know whether the 77 has been certified for 300 minutes on Extended Operations (ETOPS) yet?
