Airwolf is the helicopter from the 1980s American eponymous television series. Its fictional features included stratospheric ceiling, stealth noise signature, a wide range of weapons and even supersonic speed. Airwolf was in fact a conventional Bell 222 helicopter modified by attaching some film props.
Hotspot (geology) In geology, a hotspot is a location on the Earth's surface that has experienced active volcanism for a long period of time.
Hot springs or thermal springs are areas where hot water comes to the surface of the Earth. Cool groundwater moves downward and is heated by a body of magma or hot rock. A hot spring results if this hot water can find its way back to the surface, usually along fault zones.
