More info required.... I have to admit and I should have mentioned this earlier I instruct heli and fixed wing and have done for the last 10yrs.. I'm use to as you put it estimating speed, hight and erm distance. In my first post I did mention the speed and hight and the ground covered in the time I had it in my sight.. If you combine all these elements you can make pretty good estimates. I do admit I didn't mention this was a half mile away... I would say that even an amature would be able to tell the difference between 20kt and 200kt at that distance. If I remember we were working with 15kt winds in the morning of the 26th with no sig change expected! So the puzzling thing is how did that tea light powered paper lantern get up to such speeds. Interesting I'm sure you'll agree! But I do agree with you on the wind direction I just checked my flight log NNE@15kt...
