I'm sitting here on the late plane from Chicago back to LA, staring into the blackness beyond my window, and on the horizon, I see flashes of lightning in the shape of small hemisperes of diffuse strobing light. The flashes are sporadic, but are every three to eight seconds between flashes. Simetimes there are two ot three separate flashes at the same time in different places. One time, almost my whole visual horizon lit up.

The frequency of the lightning is getting shorter. Now, it's usual to see flashes in five different places, the bursts are relentless! As we fly closer to the storms, the lightning illuminates some of the ground. We are near Kansas and Colorado.

This is one of the most spectacular things I've ever seen.
