How common is ball lightning?

Is Ball Lightning a real thing?
Ball lightning is an unexplained phenomenon described as luminescent, spherical objects that vary from pea-sized to several meters in diameter.
What is a lightning leader?
Stepped leaders develop within thunderstorm clouds when charge differences between the main region of negative charge in the middle of the thunderstorm and the small region of positive charge near the base of the storm become large (Figure 1).
Has anyone been killed by ball lightning?
Ball lightning is usually harmless; a glowing ball of ethereal light often seen gliding or flying through the air. In rare cases it can be dangerous. This tragic story appears to have been the first recorded case of deaths from ball lightning.
Are planes safe from lightning?
Lightning usually strikes an aircraft on a sharp edge like the wing, nose or antennas. The electricity then flows through the wiring and exits the tail of the plane. They can fly the plane without all the modern technology in the event of an emergency.
Are sprites related to lightning?
Lightning sprites are electrical discharges high in Earth’s atmosphere. They’re associated with thunderstorms, but they’re not born in the same clouds that send us rain. Sprites are often triggered by a strong, positive bolt of ordinary lightning near the ground.
Does red lightning exist?
Red lightning, or more commonly known as sprites, is an electrical discharge that appears as a burst of red light above the clouds during a thunderstorm. Red lightning is associated with the positive lightning strokes that take place once the cloud has a positive charge build up and releases a lightning bolt.
What does it mean when lightning is green?
Green lightning does indicate that the cloud is extremely tall, and because thunderclouds are the tallest clouds, green is a warning sign that large hail or a tornado is on the way. Green lightning has only been photographed once when the Chaiten volcano in Chile erupted. Spewing an ash cloud into the atmosphere.
