A rocket engine exploded during a test launch at the SaxaVord Spaceport in the Shetland Islands, Scotland, on Monday evening, according to German manufacturer Rocket Factory Augsburg (RFA).

No injuries were reported. Video footage showed the engine exploding on the launchpad, engulfing the structure in flames and thick smoke.

The spaceport, recently licensed by the Civil Aviation Authority, is the only fully-licensed vertical rocket launch port in Western Europe and is intended for small rockets delivering payloads into low Earth orbit.

RFA was conducting tests ahead of the U.K.’s first vertical rocket launch, planned for this autumn.

The company stated that the launch pad was secured, the situation is under control, and an investigation is underway, ABC News has reported.

Britain aims to become Europe’s leader in commercial spaceflight, with another licensed spaceport in Cornwall, where rockets are launched horizontally.
