In the United States, a Hare & Hound is a type of off-road racing event where the entrants compete on dirt bikes over a marked course of natural rugged terrain.
Identification, friend or foe (IFF) is an identification system designed for command and control.
An immobiliser or immobilizer is an electronic security device fitted to an automobile that prevents the engine from running unless the correct transponder car key (or other token) is present.
The International Maritime Organization (IMO), known as the Inter-Governmental Maritime Consultative Organization (IMCO) until 1982, is a specialised agency of the United Nations responsible for regulating shipping.
A landline telephone (also known as land line, land-line, main line, home phone, landline, fixed-line, and wireline) is a phone that uses a metal wire or optical fiber telephone line for transmission as distinguished from a mobile cellular line, which uses radio waves for transmission.
The Lockheed SR-71 "Blackbird" is a long-range, Mach 3+ strategic reconnaissance aircraft that was operated by the United States Air Force.
