SpaceX to build test prototype of BFS, test on Falcon 9

Capitalism in space: SpaceX announced today that it is building a test prototype of its Big Falcon Spaceship, the upper stage of its Big Falcon Rocket, and it will use the Falcon 9 to do orbital flight tests.

Musk in a tweet said that they hope to to do the first flight by June 2019. Musk also said that they will not be testing vertical landing with this prototype, focusing instead on atmospheric re-entry. From this I can only assume it will not be recovered after its return to Earth.
