Virgin Orbit’s first launch demonstration flight has ended in a very unceremonious fashion. The spaceflight firm reported a “clean release” of LauncherOne from the Cosmic Girl host aircraft, but the rocket’s journey “terminated shortly into the flight.” In other words, LauncherOne didn’t have a realistic chance of reaching orbit.

The company had warned that the flight might not end well. This was the first time anyone had lit up a liquid-fuelled rocket at high altitude in a horizontal position, and it wasn’t clear if the rocket would last more than a brief moment.
