Complete silence—suggesting all/both the engines have failed—would probably concern most. But even then, all is not lost—if the engines can't be restarted, planes can actually glide for a remarkable distance. After Air Transat Flight 236 lost power on August 24, 2001, it managed an emergency landing in the Azores after gliding for 120km.
