The KC-135 Stratotanker, designed and manufactured by Boeing, is a four-engine jet aircraft developed to provide aerial refueling capability, a fundamental element in modern military aviation and strategic deployments. This aircraft has served the armed forces of various nations, primarily the United States Air Force (USAF), functioning as a strategic platform that extends the range, endurance, and payload capacity of combat and bomber aircraft. The KC-135 is one of the rare fixed-wing aircraft

The fuel crisis in Cuba is an energy and transportation-related supply issue that became evident in early 2026 due to disruptions in the supply of petroleum products, particularly jet fuel, leading to the suspension of fueling operations for international airlines at Cuban airports.The fuel crisis in Cuba became visible in early 2026 through interruptions in jet fuel supply that directly affected the country’s civil aviation system. The crisis gained public attention when fueling operations for

Hydrogen fuel systems encompass the technologies and equipment that convert the chemical energy of hydrogen into usable power. In these systems, hydrogen generates energy either through combustion or via electrochemical reactions to produce electricity. Structurally, they consist of storage units, transmission lines, pressure and temperature control mechanisms, and safety sensors.In general terms, hydrogen fuel systems refer to the technological infrastructure that uses hydrogen as an energy car

Crash of a U.S. KC-135 Aerial Refueling Aircraft in Iraqi Airspace is a military aviation accident that occurred on 12 March 2026 when a KC-135 Stratotanker aerial refueling aircraft under the command of U.S. Central Command (CENTCOM) crashed west of Iraq. The incident took place during the U.S. campaign against Iran known as the “Epic Fury” operation, during which one of the two involved aircraft landed safely while the other crashed. CENTCOM stated that the crash was not caused by enemy or fri

In March 2026 a widespread power outage occurred across Cuba. Due to a technical failure in the national electricity system millions of people in the western and central regions were left without power. Energy supply was completely halted in numerous cities including the capital Havana. The outage resulted in the collapse of the national grid causing temporary shutdowns of generation and transmission activities across the system.It was reported that the outage originated from a serious malfuncti

Kerosene (or paraffin oil) is a lightly viscous hydrocarbon fuel obtained by refining crude oil. It is colorless or pale yellow in color and is commonly used as jet fuel heating oil and for lighting. It is a flammable liquid with a density between gasoline and diesel.Chemical Composition and ProductionKerosene consists primarily of hydrocarbon chains in the C₁₂–C₁₅ range, mostly alkanes and cycloalkanes. It is produced by distilling crude oil between 150°C and 275°C. During the refining process,

A carburetor is a component found in motor vehicles that mixes air and fuel required for the engine to operate. It is commonly used in older model cars and motorcycles. For the engine to function properly, the ratio of fuel and air entering it is critical. The carburetor is the device that regulates this ratio.What Is the Purpose of a Carburetor?An engine requires fuel, typically gasoline, and air to operate. The carburetor mixes these two substances in the correct proportion and delivers the mi
