Development of the three branches of gigantic jet 7 recorded by the high speed camera. Image sequences recorded at 0.2 ms intervals, showing the upward speed of the development, and their brief downward extending parts indicated by a dotted line. a the first right-hand branch, with a clear bidirectional onset, b the second right-hand branch, overlapping visually with remnants of the first, c the third branch, occurring to the left of the others, with a subtle downward component
