I had this plane so high all I could see was a dot the size of a pencil lead and which way it was going. No outline features were visible. But at normal altitudes, transparent coverings are easily seen.

BTW... I lost this plane April 15, 2003. I got a call tonight from someone who thinks they found it. Unfortunately, it was a message on my machine, so I haven't called back to verify. It has been outdoors in heavy winds and rains and all last summer (Florida), so it's probably toothpicks. Even so, I'll be glad to have her back.
