If you think it would never happen to you, then how about this. En-route Townsville to Darwin in a Lincoln bomber in the 1950's, the AH toppled terminally leaving the pilot flying at night with primary panel only - meaning the Turn and Bank indicator. This happened at the half-way point with three hours to go. Due seasonal weather aircraft in cloud most of the way but when not in cloud was black night IMC. The aircraft arrived over Darwin about one hour before dawn. Rather than risk an instrument let down on the Turn and Bank indicator, the pilot elected to fly within a 20 mile radius of the airport until as the sun came up he could see holes in the cloud. He then let down through the holes until visual with the ground and airport.
