Diagram of a simple time bomb in the form of a pipe bomb. The explosive charge is the main component of any bomb, and makes up most of the size and weight of it. It is the damaging element of the bomb (along with any fragments or shrapnel the explosion might produce with its container or neighboring objects).
However, some electronic delays developed by IRA technicians could be set to accurately detonate a bomb weeks after it was hidden, which is what happened in the Brighton hotel bomb attack of 1984. Initially, bombs were detonated either by timer or by simple command wire. Later, bombs could be detonated by radio control.
The atomic bomb explosion generated a windstorm several kilometers wide that carried ash, dust, and debris over the mountain ranges surrounding Nagasaki. Approximately 20 minutes after the bombing, a black rain with the consistency of mud or oil came down carrying radioactive material for one to two hours before turning clear. [227]
Time fuzes detonate after a set period of time by using one or more combinations of mechanical, electronic, pyrotechnic or even chemical timers. Depending on the technology used, the device may self-destruct [ 21 ] (or render itself safe without detonation [ 22 ] ) some seconds, minutes, hours, days, or even months after being deployed.
The resulting explosion would be called a "fizzle" by bomb engineers and weapon users. Plutonium's high rate of spontaneous fission makes uranium fuel a necessity for gun-assembled bombs, with their much greater insertion time and much greater mass of fuel required (because of the lack of fuel compression).
The bomb was released from its clamps and fell on the bomb bay doors, which held for a “second or two,” before breaking open and dropping a military-grade warhead on the Gregg home just east ...
A delay-action bomb is an aerial bomb designed to explode some time after impact, with the bomb's fuzes set to delay the explosion for times ranging from very brief to several weeks. Short delays are used to allow the bomb to penetrate before exploding: "a delay action bomb striking the roof of a tall building will penetrate through several ...
The ten-minute sequence capturing the first-ever successful atomic bomb detonation came together through many experiments. It was a given that Nolan would do the scene in-camera.
