Pan Am Flight 103 (PA103/PAA103) was a regularly scheduled Pan Am transatlantic flight from Frankfurt to Detroit via a stopover in London and another in New York City. Shortly after 19:00 on 21 December 1988, while the Boeing 747 "Clipper Maid of the Seas" was in flight over the Scottish town of Lockerbie, it was destroyed by a bomb, killing all 243 passengers and 16 crew aboard.

It does not fizz or make any other noise. However, unlike clockwork timers, pencil detonators only give approximate time delays. For example, a 2-hour pencil detonator might be accurate to plus or minus 5 minutes, whereas the version offering a 6-hour delay could have a precision of plus or minus 15 minutes.
Nuclear bomb designed to fit inside a suitcase. 1950s Thermometric bomb: Also called a vacuum bomb, or aerosol bomb, this explosive disperses a cloud of gas or liquid. Time bomb: A bomb that is triggered by the timer. Trinitrotoluene: Commonly known as TNT. 1863 Julius Wilbrand: Germany: Unguided bomb: An air-craft dropped bomb that lacks a ...
A time bomb's timing mechanism may be professionally manufactured either separately or as part of the device, or it may be improvised from an ordinary household timer such as a wind-up alarm clock, wrist watch, digital kitchen timer, or notebook computer. The timer can be programmed to count up or count down (usually the latter; as the bomb ...
Laydown delivery is a mode of delivery found in some nuclear gravity bombs: the bomb's descent to the target is slowed by parachute so that it lands on the ground without detonating. The bomb then detonates by timer some time later. [1] Laydown delivery requires the weapon to be reinforced so that it can survive the force of impact. [2]
An accurate rule of thumb, applicable in the time-period of days to a few weeks post-detonation which approximates the radioactive dose rate generated by the decay of the myriad of isotopes present in nuclear fallout, is the "7/10 rule". [133] [105] The rule states that for each 7-fold increase in time the dose rate drops by a factor of 10. [134]
A barrel bomb is an improvised unguided bomb, sometimes described as a flying IED (improvised explosive device). They are typically made from a large barrel -shaped metal container that has been filled with high explosives , possibly shrapnel , oil or chemicals as well, and then dropped from a helicopter or aeroplane.

The two male bombers armed the bomb and set the timer to detonate it in forty minutes. [31] They left the car and walked east down Market Street towards Campsie Road, before leaving Omagh in the scout car. [31] A family of Spanish tourists happened to take photos next to the car; the man and child in the photograph survived but the photographer ...
