Laurent Aigon, a waiter by trade, built his son a fully-functional flight simulator cockpit for a 737 in his room. The simulator was so accurate and well-made that it's attracted the attention of local pilots who use it for real training!
Lightning is awesome and today the Department of Awesome Natural Phenomena presents a form of lightning we'd never heard of before: blue jet lightning. This is a form of upper-atmospheric lightning, believed to be electrically induced forms of luminous plasma. It's also known as a transient luminous event (or TLE) because the various types of electrical-discharge phenomena in the upper atmosphere lack several characteristics of the more familiar tropospheric lightning.
