looking at high up airoplane ans strange effect
i wonder if you can help me? i am a regulary spotter of airplanes that go overhead of my house. they are very high up, usually about 60,000foot so thatt i can see the tacks coming out og the engines making water droplets into the atmosfere (contrains).
has any one seen the following? if the airoplane is going into high up cloud a little bit, i sometimes see an strange effect. the front of the plane is a line that seen to go strait ahead and cut through the high cloud. is this the microwave beem from the airoplanes radar or is it just a trick of the eye?
normally i dont see it, especially when its too cloudy, but wen i do its weird.
can anyone offer a light on this effect?
