Stratolaunch’s chief operating officer Zachary Krevor said on Thursday: "Today’s flight, at first review, has appeared extremely successful.

"We accomplished all test points as desired, we have not seen anything anomalous, and we are very pleased with the condition of the aircraft upon landing."

The Roc plane was tested over the Mojave Desert in California.

It reached a peak altitude of 2.6 miles just after 10.30am ET yesterday.

Six engines kept it flying for three hours and 14 minutes before it touched down on an equally huge runway.

The plane is designed to operate under a three-person crew which includes a pilot, co-pilot and flight engineer.

It looks like it has two cockpits but a pilot and co-pilot only sit on the right side of the plane.

The left nose is unpressurised and is said to contain flight data systems.

The Roc plane is being designed to be an airborne space launch platform.

It will carry hypersonic flight rockets up into the low Earth orbit.

This will include Stratolaunch’s fully reusable and autonomous Talon-A hypersonic aircraft.

The Roc aircraft still has more tests to go before it will be trusted to carry anything though.In other news, China appears to be developing a knockoff version of SpaceX's next-generation rocket as it moves to enter a new space race with the US.

Nasa completed the first controlled flight on another planet following the lift-off of its Mars helicopter-drone, Ingenuity.

And, a supersonic plane that could fly you from London to New York in an hour is in the works.
