Mounted film and noticed that something took off from the grass and the frenzied speed went to the upper left corner. slow repetition (10% of the rules of the velocity) can be seen better but still not enough to stop the frame shows that this is not an insect. The speed was 270 km / hr. Treat yourself. Visually prletel 6 pm for 2 frames. The camera shoots 25 frames / sec. What was that???
