Boeing 747 in the context of "Pan Am"

Aviation includes the activities surrounding mechanical flight and the aircraft industry. Aircraft include fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air aircraft such as hot air balloons and airships.

Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Clément Ader built the "Ader Éole" in France and made an uncontrolled, powered hop in 1890. This was the first powered aircraft, although it did not achieve controlled flight. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896. A major leap followed with the construction of the Wright Flyer, the first powered airplane by the Wright brothers in the early 1900s.

A unit load device (ULD) is a container used to load luggage, freight, and mail on wide-body aircraft and specific narrow-body aircraft. It allows preloading of cargo, provided the containerised load fits in the aircraft, enabling efficient planning of aircraft weight and balance and reduced labour and time in loading aircraft holds compared with 'bulk-loading' single items of cargo or luggage by hand. Each ULD has its own packing list or manifest so that its contents can be tracked. A loaded aircraft cargo pallet secured with a cargo net also forms a ULD, but its load must be gauged for size in addition to being weighed to ensure aircraft door and hold clearances.

The IATA publishes ULD regulations and notes there are 900,000 in service worth more than US$1 billion, averaging $1100 each.

An international airport is an airport with customs and border control facilities, enabling passengers to travel between countries around the world. International airports are usually larger than domestic airports, and feature longer runways and have facilities to accommodate heavier aircraft such as the Boeing 747 and the Airbus A380 commonly used for international and intercontinental travel. International airports often host domestic flights, which helps feed both passengers and cargo into international ones (and vice versa).

Buildings, operations, and management have become increasingly sophisticated since the mid-20th century, when international airports began to provide infrastructure for international civilian flights. Detailed technical standards have been developed to ensure safety and common coding systems implemented to provide global consistency. The physical structures that serve millions of individual passengers and flights are among the most complex and interconnected in the world. By the second decade of the 21st century, over 1,200 international airports existed with around 3.8 billion international passengers as of January 2023 along with 50 million metric tonnes of cargo passing through them annually.

Dzaoudzi–Pamandzi International Airport (IATA: DZA, ICAO: FMCZ) is an airport located in Pamandzi, Mayotte, France on the southern tip of the island of Petite-Terre (or Pamanzi), east of Grande-Terre, the main island of Mayotte. It is the only airport in Mayotte with scheduled services, mainly to destinations within Africa to Réunion, another French island in the area. The airport was able to service aircraft up to the Boeing 777 in size until 2015.

A new runway (16/34) to the west of the original single runway was planned, and was built 2,600 metres in length to accommodate larger aircraft such as the Airbus A380 and Boeing 747. Once built, the older runway became a taxiway. There was also a new terminal built to replace the previous departure and arrival buildings. This project was completed in 2015. The headquarters of Ewa Air are located on the airport property.

Wake Island (Marshallese: Ānen Kio, lit. 'island of the kio flower'), also known as Wake Atoll (Chamorro: Islan Wake), is a coral atoll in the Micronesia subregion of the Pacific Ocean. The atoll is composed of three islets – Wake, Wilkes, and Peale Islands – surrounding a lagoon encircled by a coral reef. The nearest inhabited island is Utirik Atoll in the Marshall Islands, located 592 miles (953 kilometers) to the southeast.

The island may have been found by prehistoric Austronesian mariners before its first recorded discovery by Álvaro de Mendaña de Neira in 1568. Ships continued visiting the area in the following centuries, but the island remained undeveloped until the United States claimed it in 1899. Significant development of the island did not begin until 1935 when Pan American Airways constructed an airfield and hotel, establishing Wake Island as a stopover for trans-Pacific flying boat routes. In December 1941 at the opening of the Pacific Theatre of World War II Japan seized the island, which remained under Japanese occupation until the end of the war in September 1945. In 1972, Pan American Airways ceased using the island for trans-Pacific layovers, instead using Boeing 747 aircraft, which could cross the ocean without stopping. With the withdrawal of Pan American Airways, the island's administration was taken over by the United States Air Force, which later used the atoll as a processing location for Vietnamese refugees during Operation New Life in 1975.

A laser weapon is a type of directed-energy weapon that uses lasers to inflict damage. Whether they will be deployed as practical, high-performance military weapons remains to be seen. One of the major issues with laser weapons is atmospheric thermal blooming, which is still largely unsolved. This issue is exacerbated when there is fog, smoke, dust, rain, snow, smog, foam, or purposely dispersed obscurant chemicals present. In essence, a laser generates a beam of light that requires clear air or a vacuum to operate.

Laser-based directed energy weapons generally have two primary types: low-power laser dazzlers that blind optical systems or human eyes, and high-power lasers that can physically damage or destroy targets, such as enemy aircraft and ammunition.
