1) filming over a lake with my drone. 2) when i played back the footage i noticed it. 3) i did not know what the object was when i established it could not have been an insect or a bird. therefore, a ufo. 4) the object was bight white no more than 2 feet i would say looking at the closer footage. looked elongated because of the speed which i was recording at and the speed it was travelling at also. and could be seen in the footage coming from over 100 ft away, it first appears at the top of the tree line moving towards the camera on the drone swooping down to about 2 mtrs. above the lake where the drone was stationary. then swooping up. the object flew towards my drone from over 100 ft away at incredible speed 19 frames in total i filmed at 30 fps. so it completed that distance in just over 1/2 second. faster than any known insect or bird known. 5) i did not see this object at the time as i was 300 meters away, it was the drone footage i saw after when editing and i was somewhat shacked that i captured not just this one but a further 4 objects two of which left a trail. i have uploaded the footage to youtube with various speeds to the footage to/for analyses. 6) the object flew out of camera shot and lost sight of it on the recorded footage.
