An unmanned scale model of the X-38 Crew Emergency Return Vehicle "space lifeboat" for the International Space Station will be deployed from the Space Shuttle Columbia in 2000 to conduct an automatic re-entry and landing. The first demonstrator glide test was on 12 March at 23,000ft (7,010m). Tests from altitudes of up to 50,000ft are planned before the vehicle goes into space.
