This supports OP point of warning lights being a nag…..
Pilot's should have ignored the nagging warning light's……
If I have to hit 'OK' button for low battery warning on my iPhone - I could potentially crash into a light post or worst in another car if I am driving…
Actually it was a lack of a light. If the gear is down and locked, you get a green light. In this case, the nose gear did NOT give a green light so they broke off the approach and went to circle in the Everglades to investigate. They wanted to replace the bulb to confirm that the gear was, in fact, down and locked. The light would have saved everyone on board. Sadly, they were all distracted by replacing the bulb. Indeed it was a crew management error, but still. . .
More regrettably, the gear was, in fact, down and locked. So if the light had worked, the people on board would not have perished in an awful crash. Sometimes warnings and indicators are a good thing.
PS - don't mess with your phone while driving. Ha ha.
