Infrared homing

Infrared homing refers to a passive weapon guidance system which uses the infrared (IR) light emission from a target to track and follow it. Missiles which use infrared seeking are often referred to as "heat-seekers", since infrared is radiated strongly by hot bodies. Many objects such as people, vehicle engines and aircraft generate and retain heat, and as such, are especially visible in the infrared wavelengths of light compared to objects in the background.

Infrared seekers are passive devices, which, unlike radar, provide no indication that they are tracking a target. This makes them suitable for sneak attacks during visual encounters, or over longer ranges when used with a forward looking infrared system or similar cuing system. This makes heat-seekers extremely deadly; 90% of all United States air combat losses over the past 25 years have been due to infrared-homing missiles. They are, however, subject to a number of simple countermeasures, most notably dropping flares behind the target to provide false heat sources. This only works if the pilot is aware of the missile, and modern seekers have rendered these increasingly ineffective even in that case.

The song was also released as a single in various formats, with "Go Zone" as the main B-side.

Music video

In the music video, directed by David Mallet,Angus Young explodes from a life-sized television set. He throws his hat, and it lands on a switch, causing it to flip. An intercontinental ballistic missile is launched, and on the screen is film footage of the Strategic Air Command in the 1950s, 1960s and 1970s. The missile becomes a cruise missile, and travels across the world, whereupon it finally crashes into the Opera House in Sydney, during an AC/DC concert. Angus explodes out of the giant missile's warhead and does a guitar solo. At the end, Angus heads back into the missile's nose cone and leaves.

Cato, a Tragedy

Cato, a Tragedy is a play written by Joseph Addison in 1712, and first performed on 14 April 1713. Based on the events of the last days of Marcus Porcius Cato Uticensis (95–46 B.C.), a Stoic whose deeds, rhetoric and resistance to the tyranny of Julius Caesar made him an icon of republicanism, virtue, and liberty. Addison's play deals with, among other things, such themes as individual liberty versus government tyranny, Republicanism versus Monarchism, logic versus emotion, and Cato's personal struggle to hold to his beliefs in the face of death. It has a prologue written by Alexander Pope, and an epilogue by Samuel Garth.

The play was a success throughout England and her possessions in the New World, as well as Ireland. It continued to grow in popularity, especially in the American colonies, for several generations. Indeed, it was almost certainly a literary inspiration for the American Revolution, being well known to many of the Founding Fathers. In fact, George Washington had it performed for the Continental Army while they were encamped at Valley Forge.
