Does anyone have an explanation for the green sky
Would like to know as well. About '63 not too long after gaining PPL departed Parafield (Adelaide) in a 172 for home 150 miles to the north. A front was moving in from the west and below the dark cloud was a very green green. Remembered also for the fact that we flew most of the trip with the power at idle, airspeed near Vne and fuel continually streaming from the vent behind the left strut (departed full tanks), remarkably the ride was as smooth as.
