green glowing triangular object fallingwhile driving on the freeway in direction of Venice, i noticed right in front of me, a falling green triangle. It was extremely bright, of a brilliant green. Object was of a perfect triangular shape and glowing, but it was possible to see clearly the edges of the shape. It was falling in curve trajectory, direction west to east.Duration of the fall approx 5 seconds.Object had to be quite big, since it had the dimension of approx 3 mm from my point of view and it was most likely at 40 km far at least.
