Reference excerpt

In October, 1982, three members of an anarchist urban guerrilla group known as Direct Action acted upon "their wish to end the arms race" and filled a stolen pick-up truck with 550 kg (1,210 lb) of dynamite and drove from Vancouver to Toronto, Canada planting the bomb outside Litton Industries, a manufacturer of American cruise missile components many feared would increase the risk of nuclear war. Although the militants had phoned to evacuate the building, the bomb was accidentally detonated several minutes before its announced deadline, injuring several bomb squad police officers and citizens in the vicinity.

Litton Industries' role Litton Industries was conceived as a radio-engineering firm in 1934, but was purchased by Charles Bates Thornton, a Pentagon official with "all the right connections in the government and military", in 1956. Litton was transformed into a military producer, building entire naval ships in their own shipyards, and installing their own equipment, including communications and navigation systems. Described as "the best known economic link between Canada and the nuclear arms race", Litton Industries' Rexdale plant was announced in October 1978 as one of two locations in the world that would be responsible for the manufacture of Terrain Contour Matching (TERCOM) guidance systems of the American Tomahawk cruise missile. The Canadian federal government had given Litton a $26.4 million grant, in addition to a $22.5 million interest-free loan specifically to allow them to bid competitively for the contract, drawing complaints from some members of the public for using federal funds to further the arms race. The American contract called for Litton Canada to produce the navigation systems for approximately 407 cruise missiles.

Planning

On the night of July 27, 1982, a British Columbia Department of Highways explosives storehouse north of Squamish was entered, and 38½ cases of dynamite were stolen. On September 13, a local hunter came upon two camouflaged and locked wooden structures that had been built in the forests of Garibaldi, near the site of the theft. One contained four reels of detonating cord and three boxes of electronic blasting caps, and the other building held 28½ cases of dynamite as well as explosive gelatin. This indicates that ten crates of dynamite were not stored in the wooden structures, to which Direct Action members Brent Taylor and Ann Hansen held keys. The three associates stole a GMC van in the Greater Toronto Area on September 30, as well as an Oldsmobile and Chevrolet Chevelle three and four nights later respectively. On the morning of October 14, just hours before the bombing, the Ontario Court of Appeals ruled that five Litton executives from the plant could not be called to testify by the defence counsel of 22 anti-nuclear activists who had been arrested for trespassing one year earlier.

Execution of the bombing The bombing was carried out on October 14, 1982, using a van that was parked in a location partially concealed by shrubs, with a fluorescent "warning box" duct taped to the hood, displaying a message, a digital clock counting down, and a single stick of dynamite.

DANGER EXPLOSIVES – Inside this van are 550 lbs. of commercial dynamite which will explode anytime from within 15 minutes to 25 minutes after the van was parked here. The dynamite will be set off by two completely separate detonating systems. Do not enter or move the van – it will explode. Phone the police immediately and have them block off Highway 27, Cityview Drive, Dixon Road and other roads surrounding the Litton plants and have the workers inside the plants moved to protected areas. Nearby hotels and factories should also be notified so that no one will be hurt by the blast. On top of this box is an authentic sample stick of the dynamite contained inside the van. This is to confirm that this is a real bomb. Belmas called the security desk and warned them that a dynamite bomb was placed in a van outside the building, and that it would detonate "in 15 to 20 minutes". She also told the guards to evacuate the plant, phone the local hotels to warn guests to stay away from windows to avoid injury and to have police close down passing roadways so that only the Litton Industries building would be damaged.

... And it will explode in 15 to 20 minutes. Do not enter or move the van because it will explode. This is no prank. We have left for you on the lawn beside the van a box, which is not dangerous. Taped to the box are further instructions and a stick of the same dynamite that we have used in the bomb. This should be ample evidence in confirming to you the severity of our attack. Act immediately to phone the police and have them block off traffic from Cityview drive, Highway 27, Dixon Road and other surrounding areas. Move all the workers from all of your plants to protected areas and notify the surrounding hotels to have people stay away from all windows. I want to be sure that you understand what I just said. Could you repeat the crucial information to me? The bomb detonated 11 minutes after the phone call. Speculation by local police constable Mitchell of the Toronto bomb squad three weeks after the bombing proposed that if responding officers had used radios, their use may possibly have triggered the detonation early. A representative of Litton also confirmed that radios were used during the evacuation of the plant. The explosion injured three members of the police, three passing motorists and five Litton employees, blowing out a 50-foot section of wall on the main two-story plant, and damaging two adjacent buildings. The cost of damages was described by police as being "in the millions". Damages were estimated anywhere from $3.87 million to $50 million. On October 19, a 9-page communiqué was mailed to various organisations and media outlets. The first six pages were titled "Direct Action" and explained the philosophy of the group's actions. The remaining three pages were titled "Statement regarding the October 14 Litton Bombing" and included an explanation of the purpose of the bombing, as well as an apology for the injuries.

Worked examples

Example 1 — a first encounter with Litton Industries bombing

Start with the simplest possible case. Write down what Litton Industries bombing claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Litton Industries bombing before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Litton Industries bombing ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Litton Industries bombing

In research
Litton Industries bombing appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Litton Industries bombing in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Litton Industries bombing is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1982 building bombings, 1982 crimes in Canada, 1982 in Toronto, so understanding it makes those chapters shorter.
In everyday life
Look for Litton Industries bombing outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
