Ultra-high-speed footage of a single stroke of lightning beginning as a cloud flash, then with stepped leaders moving earthwards, until one connects with an upward leader from the ground to create the brilliant return stroke. An upward discharge off a nearby tower also is evident. Filmed at 7200 frames per second, in South Dakota, USA, in summer. | |
