I threw that in because I knew that it wasn't until 1929 that Doolittle demonstrated instrument flying, that allowed safe flight in the dark, fog, etc.
But I guess that even at night, if conditions were right, you could fly a plane. And people did during WW I. Though the descriptions in http://www.century-of-flight.net/Aviation%20history/airplane... of the practical problems in landing when you didn't know how close the field was are somewhat harrowing.
