hypersonic vehicles

This artist’s concept drawing shows how the Towed-Glider Air Launch System, or TGALS, would work. A business jet-class aircraft would tow a remotely piloted glider with a launch vehicle mounted underneath it. Once released at about 40,000 feet, the glider uses its own small rocket motor to execute a pull-up maneuver, releasing the launch vehicle for ignition at an elevated flight path angle. Credits: NASA
