A photo of an oil on canvas on two ME109s being pursued at a dangerously low level by ywo RAF Spitfires. It may not have been sensioble or possible to fly this low, but I claim artists licence.
Dangerous, yes. Sensible, depends on the circumstance. As a kid, watching the air war unfold over North London I saw a Typhoon as low as this still trying to nail a suicidal 'buzz bomb'.
The painting's great, as is 'Skimming'.
