Inside Virgin Galactic's top-secret spaceship factory

4 June 2015 Last updated at 09:16 BST

Virgin Galactic are building a new space plane in a top-secret hanger in the California Desert.

The company wants to take paying passengers on tourism trips into space, but they've faced big questions over how safe this form of travel is.

Last November a Virgin Galactic spacecraft crashed during a test run.

There were no passengers on board but one pilot was killed.

It led to big questions over whether this form of travel really is safe.

The BBC's Richard Westcott sent us this special report from Virgin's spaceship factory.
