Supersonic transport refers to aircraft capable of flying faster than the speed of sound, which is approximately 343 meters per second (1,125 feet per second) at sea level in dry air at 20°C (68°F). This speed is commonly referred to as Mach 1. Aircraft designed for supersonic transport are typically characterized by their aerodynamic shapes, powerful engines, and specialized design features to handle the challenges associated with flying at such high speeds.

A supersonic business jet (SSBJ) is an advanced type of business aircraft designed to travel faster than the speed of sound, typically exceeding Mach 1 (approximately 1,235 kilometers per hour or 767 miles per hour at sea level). These jets aim to significantly reduce flight times on long-distance travel, allowing business travelers to spend less time in transit and more time at their destinations.

The Sud Aviation Super-Caravelle is a French twin-engine jet airliner that was developed in the 1960s. It is an extended version of the earlier Sud Aviation Caravelle, which was one of the first jets designed specifically for short and medium-haul passenger flights. The Super-Caravelle featured improvements in range, capacity, and performance compared to its predecessor.

"Some Girls Do" is a song by the American rock band Racey, released in 1978. It was part of their debut album, "Smash and Grab." The track is known for its upbeat tempo and catchy melody, characteristic of the pop-rock and power pop genres of that era. The band Racey gained some popularity in the late 1970s and early 1980s, particularly in the UK.

The LAPCAT A2 (Long-term Advanced Propulsion Concept for Air Transport) is a conceptual aerospace vehicle developed by Reaction Engines Limited. It is designed as a high-speed air transport system that seeks to combine the functionality of a subsonic airliner with the speed of a hypersonic vehicle. The LAPCAT A2 aims to achieve cruise speeds of around Mach 4, which is four times the speed of sound, enabling long-distance travel that could significantly reduce flight times.

The North American NAC-60 is a specification used in the field of electrical testing and standards. Specifically, NAC-60 refers to a standard for the use of electric vehicle (EV) charging systems in North America, particularly focusing on the interoperability and safety of EV infrastructure. The NAC (National Electrical Code) designation is related to electrical installations and outlines requirements aimed at ensuring safety for electrical systems, including those that involve high voltage and current used for charging electric vehicles.

Next Generation Supersonic Transport (NGST) refers to ongoing efforts and projects aimed at developing advanced supersonic passenger aircraft that can travel faster than the speed of sound (Mach 1), while also addressing many of the environmental, economic, and regulatory challenges that limited the success of earlier supersonic jets, such as the Concorde.

The McDonnell Douglas High Speed Civil Transport (HSCT) was a proposed supersonic transport aircraft project initiated by McDonnell Douglas in the late 1980s and early 1990s. The aircraft was intended to provide faster-than-sound air travel for commercial passengers, potentially reducing transcontinental flight times significantly compared to conventional subsonic jets. The HSCT project aimed to achieve cruise speeds of around Mach 2.

The Lockheed Martin X-59 QueSST (Quiet Supersonic Technology) is an experimental aircraft being developed by Lockheed Martin in collaboration with NASA. Its primary objective is to demonstrate technologies that could enable supersonic flight over land while significantly reducing the sonic boom associated with such flight.

The Lockheed L-2000 was a proposed supersonic transport (SST) aircraft designed by Lockheed in the 1960s. It was part of a wider effort during that era to develop commercial aircraft capable of flying faster than the speed of sound, similar to the Concorde and the Boeing 2707, which were also in development at the time.

A list of supersonic aircraft includes various types of military and civilian aircraft that have the capability to exceed the speed of sound (approximately 343 meters per second or 1,125 feet per second at sea level). Here’s a list that highlights some notable supersonic aircraft: ### Military Supersonic Aircraft 1. **Bell X-1** - The first aircraft to break the sound barrier, flown by Chuck Yeager in 1947.

LAPCAT, which stands for "LAnked Public Collection of ATaxonomical data," is a conceptual framework or project aimed at creating a comprehensive, organized database of taxonomical data. It focuses on making taxonomic information more accessible for research and educational purposes. The goal is to compile and standardize information regarding various species, their classifications, and related data in a manner that is easily searchable and usable for scientists, researchers, and educators.

HyperMach SonicStar is a concept for a high-speed aircraft designed to travel at speeds significantly exceeding that of traditional commercial airliners. HyperMach, the company behind SonicStar, envisions an aircraft capable of supersonic travel, which means it would travel faster than the speed of sound. The SonicStar is aimed at revolutionizing air travel by significantly reducing flight times on long-distance routes.

High Speed Civil Transport (HSCT) refers to advanced concepts in aviation technology aimed at developing faster, more efficient commercial aircraft that can operate at speeds significantly higher than those of conventional commercial jets. The term often encompasses both the technological innovations required to achieve high-speed travel—such as supersonic and hypersonic flight—and the economic, regulatory, and environmental considerations that come with it.

Hermeus is an aerospace company focused on developing hypersonic travel technology. Founded in 2018, the company aims to create faster and more efficient methods of air travel by designing aircraft capable of flying at hypersonic speeds, which are generally defined as speeds greater than Mach 5 (five times the speed of sound). Hermeus's approach involves advanced propulsion systems, including ramjet and turbojet engines, to achieve these high speeds.

Douglas 2229 refers to a specific genetic mutation in the *Drosophila melanogaster* species, commonly known as the fruit fly. It is notable for its association with certain phenotypic characteristics, particularly in the context of research related to genetics and developmental biology. The designation "Douglas" often denotes the name of the researcher or lab associated with the discovery or study of this mutation.

The Convair Model 58-9, also known as the Convair 58-9 or simply Convair 58, is a prototype aircraft developed by Convair, which was a division of General Dynamics. This aircraft was conceived as a potential military transport and reconnaissance platform during the early Cold War era.

Concorde was a turbojet-powered supersonic passenger airliner that was operated from 1976 until 2003. It was a joint project between British Aircraft Corporation (BAC) and Aérospatiale of France. Known for its distinctive design, characterized by its pointed nose that could be drooped for improved visibility during takeoff and landing, Concorde was capable of cruising at over twice the speed of sound, typically around Mach 2.04.

The Bristol Type 223 was a British aircraft design developed in the 1940s by the Bristol Aeroplane Company. It was intended as a medium bomber for use by the Royal Air Force after World War II. The design of the Type 223 featured a twin-engine configuration and was notable for its intended use of advanced aerodynamics and technology for its time. However, the Bristol Type 223 never reached production. As military priorities and technologies evolved post-war, the project was eventually abandoned.
