Warning lights - a scenario
What if the warning light went out because the wire burnt through?
Yes I know "Matilda told such awful lies it made one gasp and stretch one's eyes..."
So... let's say a known occurrence occurs and CRM is followed and the consensus is that it is that microswitch again and an edict says we'll do it "shortly". So... wheels down, wheels up, light goes out. Dam' microswitch. Except it wasn't. All perish.
