A mushroom cloud is a distinctive mushroom-shaped flammagenitus cloud of debris, smoke, and usually condensed water vapour resulting from a large explosion. The effect is most commonly associated with a nuclear explosion , but any sufficiently energetic detonation or deflagration will produce a similar effect.
The crash of Flight 182 was preceded by a near-tragedy almost ten years earlier (also involving Pacific Southwest Airlines), when, on January 15, 1969, a PSA Boeing 727-214 (#N973PS) had collided with Cessna 182L (#N42242) on-ascent from San Francisco International Airport, bound for Ontario International Airport.
Aerial footage from the recycling plant in Oxford which was struck by lightning last night (2 October), shows the damage sustained following the incident. The explosion could be heard up to 20 ...
The observed colors of the illumination changed from purple to green and eventually to white. The roar of the shock wave took 40 seconds to reach the observers. It was felt over 100 miles (160 km) away, and the mushroom cloud reached 7.5 miles (12.1 km) in height. [108] Many observers recalled their amazement at the light from the explosion.
Nancy Baker Cahill's augmented reality public art work, which launches on Monday of Frieze Week, depicts a mushroom cloud — 'the ultimate symbol of human-caused cataclysm.'
The mushroom cloud reached a height of 47,000 feet (14,000 m) and a diameter of 7 miles (11 km) in about a minute, a height of 130,000 feet (40 km) and 62 mi (100 km) in diameter in less than 10 minutes and was expanding at more than 160 meters per second (580 km/h; 360 mph).

The cumulonimbus flammagenitus cloud (CbFg), also known as the pyrocumulonimbus cloud, is a type of cumulonimbus cloud that forms above a source of heat, such as a wildfire, nuclear explosion, or volcanic eruption, [5] and may sometimes even extinguish the fire that formed it. [6] It is the most extreme manifestation of a flammagenitus cloud.
