A U.S. Air Force F-35A Lightning II in flight. Operations of the Lockheed Martin F-35 Lightning II family began in 1995 with the Joint Strike Fighter program.Since its first flight in 2006, the aircraft has faced substantial controversy, shortages in its research and development supply, [1] and safety concerns due to incidents.

Runaway breakdown is a theory of lightning initiation proposed by Alex Gurevich in 1992. [ 1 ] [ 2 ] Electrons in air have a mean free path of ~1 cm. Fast electrons which move at a large fraction of the speed of light have a mean free path up to 100 times longer.
A lightning strike or lightning bolt is a lightning event in which the electric discharge takes place between the atmosphere and the ground. Most originate in a cumulonimbus cloud and terminate on the ground, called cloud-to-ground (CG) lightning.
The sight of lightning forking from the clouds to the ground is frightening enough. But flip that upside down? That's the perfect recipe for some terrifying footage, well worth going viral. On the ...
The electrostatic repulsion of ions, ionic recombination, and air convection currents due to heating tend to break up ionized regions, so streamers have a short lifetime. In electromagnetism , a streamer discharge , also known as filamentary discharge , is a type of transient electric discharge which forms at the surface of a conductive ...
Lightning injuries are divided into direct strikes, side splash, contact injury, and ground current. [1] Ground current occurs when the lightning strikes nearby and travels to the person through the ground. [1] Side splash makes up about a third of cases and occurs when lightning strikes nearby and jumps through the air to the person. [1]
Electrical breakdown in an electric discharge showing the ribbon-like plasma filaments from a Tesla coil.. In electronics, electrical breakdown or dielectric breakdown is a process that occurs when an electrically insulating material (a dielectric), subjected to a high enough voltage, suddenly becomes a conductor and current flows through it.
Since air is invisible, what would airbending look like in real life? Fans of “Avatar: The Last Airbender” have pondered that question since the announcement of a live-action version of the ...
