Sensible lady !..notably with her ending.
Maps, and gliding, well yes they did come in useful....however, it did help when the heroic pilot could be more accurate as to the location..." in a field with tree's at one end and cows in the other " didn't really give an accurate location.
Some crews would look at the task, and then position themselves at say a mid point on a leg....some crews had more money than sense however....most of us just sat, and waited.
