Countdown

A countdown is a sequence of backward counting to indicate the time remaining before an event is scheduled to occur. NASA commonly employs the term "T-minus" during the preparation for and anticipation of a rocket launch, and even "E-minus" for events that involve spacecraft that are already in space, where the "T" could stand for "Test" or "Time", and the "E" stands for "Encounter", as with a comet or some other space object. Other events for which countdowns are commonly used include the detonation of an explosive, the start of a race, the start of the New Year, or any anxiously anticipated event. An early use of a countdown once signaled the start of a Cambridge University rowing race. The first known association with rockets was in the 1929 German science fiction movie Die Frau im Mond (English: Woman in the Moon) written by Thea von Harbou and directed by Fritz Lang in an attempt to increase the drama of the launch sequence of the story's lunar-bound rocket.

Rocketry

A countdown is a carefully devised set of procedures ending with the ignition of a rocket's engine. Depending on the type of vehicle used, countdowns can start from 72 to 96 hours before launch time.

Inch

An inch (plural: inches; abbreviation or symbol: in or ″ – a double prime) is a unit of length in the imperial and United States customary systems of measurement. Historically an inch was also used in a number of other systems of units. Traditional standards for the exact length of an inch have varied in the past, but since July 1959 when the international yard was defined as 0.9144 metres, the international inch has been exactly 25.4 mm. There are 12 inches in a foot and 36 inches in a yard.

Usage

The inch is a commonly used customary unit of length in the United States,Canada, and the United Kingdom. For the United Kingdom, guidance on public sector use states that since 1 October 1995, without time limit, the inch (along with the foot) is to be used as a primary unit for road signs and related measurements of distance (with the possible exception of clearance heights and widths) and may continue to be used as a secondary or supplementary indication following a metric measurement for other purposes.

Inch High, Private Eye

Inch High Private Eye is a 30-minute Saturday morning animates series produced by Hanna-Barbera Productions and broadcast on NBC from September 8, 1973, to August 31, 1974. Since the 1980s it has received a resurgence on cable television in the US, in repeats on USA Cartoon Express, Cartoon Network (as part of the Mysteries, Inc. block) and Boomerang.

Plot

The titular character of Inch High Private Eye is a miniature detective (literally one inch high). Inch often enlists the help of his niece Lori (sometimes written "Laurie"), her muscle-bound friend Gator, and their dog Braveheart to help solve mysteries. Their primary mode of transportation is the Hushmobile, a streamlined car that makes virtually no noise while being driven, making it perfect for following criminals unnoticed. Inch works for The Finkerton Detective Agency (a wordplay lampoon of The Pinkerton Detective Agency), where the boss (Mr. Finkerton) constantly dreams of the day that he will fire him.
