me and my kids we had a lot of opportunities of this type of events but this one was the most clear and with the tree beside my window and other house at backgrownd that could be used for your analisys.It flashed while we observed it and when i decided to take the pictures i was convinced tha i could do it becose it's speed of hovering and changing direction. But when i saw i got surprised.Please take a minute at least observing it and tell me something.I will send you the two for confirming my surprise.the first is onli a crazy line and the second shows a incredible stop time of the object.I thank you in advance for your work.David Isaac
