So flying back from Costa Rica above El Salvador I saw this storm cloud out the airplane window. There was lightning in the cloud but it was hard to catch being night time and having to hand hold the camera as well as try to catch a series of lighting. Most of them were just the clouds glowing but I lucked out on this shot.
