boo says "Have you ever seen lace made out of lightning?"

Can't remember which flight. London to KL? KL to London? Irrelevant detail. Aircraft way above the cloud line. Dark but not pitch black. Advanced dusk. Cabin lights out. Most passengers quietly dozing under blankets. I like it like this when all is still and dark on a plane. I peered out the window aimlessly. Then I saw it. Spreading out from the beneath the aircraft was this awesome silver lightning transmitting across the carpet of clouds all the way to the horizon. That very moment, I named it Lightning Lace.
