English: A simple graphic showing comparative nuclear fireball radii for a number of different tests and warheads. From largest to smallest, the diameter are: Tsar Bomba — 50 Mt — 4.6 km (2.9 mi) Castle Bravo — 15 Mt — 2.84 km (1.76 mi) W59 warhead (Minuteman missile) — 1 Mt — .96 km (0.60 mi)
Castle Bravo was the first in a series of high-yield thermonuclear weapon design tests conducted by the United States at Bikini Atoll, Marshall Islands, as part of Operation Castle. Detonated on 1 March 1954, the device remains the most powerful nuclear device ever detonated by the United States and the first lithium deuteride -fueled ...
Comparative fireball radii for a selection of nuclear weapons. [citation needed] Contrary to the image, which may depict the initial fireball radius, the maximum average fireball radius of Castle Bravo, a 15-megatonne yield surface burst, is 3.3 to 3.7 km (2.1 to 2.3 mi), [6] [7] and not the 1.42 km displayed in the image.
Operation Castle was an unqualified success for the implementation of dry fuel devices. The Bravo design was quickly weaponized and is suspected to be the progenitor of the Mk-21 gravity bomb. The Mk-21 design project began on 26 March 1954 (just three weeks after Bravo), with production of 275 weapons beginning in late 1955.

There have been some reports of a meteor (fireball) CBS 6 reports: At about 10:15 p.m. on Thursday, many of you reported seeing a bright fireball in the sky. Meteor fireball spotted over Virginia
The landmark district encompasses an area of about 20,000 acres (81 km2), including the entire city limits of Virginia City and a significant portion of Alder Gulch where mining operations took place. Many of the city's buildings were built before the turn of the 20th century, and a significant number date to its heyday in the 1860s.
