Getting some lovely evening light means the steady improvement in shooting conditions right up until the point when it all goes away. The light was on the nose of the departing jets so was good as they climbed out. Once they were passed our location, they were partially backlit but, since the sun was very low in the sky, the undersides of the jet were illuminated as it climbed. This provided some great options.
As the sun got even lower, the shade was beginning to be an issue for the front shots but the sky still provided a few nice options as the jets were heading away. The back of a plane might not always be the best side to shoot but, if the light is playing ball, it can be good. Of course, the transformation from great to gone is pretty quick so you make the best of it and then you can go home!
