McVeigh's army buddy, Michael Fortier, was sentenced to 12 years in federal prison and ordered to pay a $75,000 fine for his role in the bombing plot (i.e. assisting in the sale of guns to raise funds for the bombing, and examining the Murrah Federal building as a possible target before the terrorist attack).

paragraph_text: Two major types of atomic bombs were developed by the United States during World War II: a uranium-based device (codenamed "Little Boy") whose fissile material was highly enriched uranium, and a plutonium-based device (see Trinity test and "Fat Man") whose plutonium was derived from uranium-238. The uranium-based Little Boy device became the first nuclear weapon used in war when it was detonated over the Japanese city of Hiroshima on 6 August 1945. Exploding with a yield equivalent to 12,500 tonnes of TNT, the blast and thermal wave of the bomb destroyed nearly 50,000 buildings and killed approximately 75,000 people (see Atomic bombings of Hiroshima and Nagasaki). Initially it was believed that uranium was relatively rare, and that nuclear proliferation could be avoided by simply buying up all known uranium stocks, but within a decade large deposits of it were discovered in many places around the world.

paragraph_text: Thermos bomb was the informal name for the AR-4, an air dropped anti-personnel mine used by the Italian Air Force during World War II. Large numbers were used against Malta and in the Middle East. It was named for its superficial appearance to a Thermos bottle, a popular brand of vacuum flask. The bomb was a cylinder long and weighing . It could be fitted with a very sensitive motion-sensitive fuze that would detonate if any attempt was made to move it, and could be lethal in the open up to around away. Because of this, unexploded Thermos bombs were normally destroyed where they fell, either by attaching a long piece of string to them and giving it a jerk, or detonating a small explosive charge next to them.

Orders for atomic bombs to be used on four Japanese cities were issued on July 25. On August 6, one of its B - 29s dropped a Little Boy uranium gun - type bomb on Hiroshima. Three days later, on August 9, a Fat Man plutonium implosion - type bomb was dropped by another B - 29 on Nagasaki. The bombs immediately devastated their targets. Over the next two to four months, the acute effects of the atomic bombings killed 90,000 -- 146,000 people in Hiroshima and 39,000 -- 80,000 people in Nagasaki; roughly half of the deaths in each city occurred on the first day. Large numbers of people continued to die from the effects of burns, radiation sickness, and other injuries, compounded by illness and malnutrition, for many months afterward. In both cities, most of the dead were civilians, although Hiroshima had a sizable military garrison.
