It's been in development by the Sparks company for more than 10 years.
This successful test, though, should keep Dream Chaser on track for a debut spaceflight within the next two years.
The Dream Chaser is only a quarter of the size that the Space Shuttle was.
Sierra Nevada's Dream Chaser spaceplane safely glided to the Edwards Air Force Base runway Saturday after being dropped from a helicopter in a free-flight test. Sierra Nevada representatives announced on Twitter Saturday. Unlike other spacecraft - the capsules that look like the vehicles that flew in the Apollo-era - the Dream Chaser has wings and wheels that allow it to land on a runway.
According to Nasa, the flight test "helped advance the vehicle under Nasa's Commercial Crew Program space act agreement, as well as helped prepare the vehicle for service under Nasa's Commercial Resupply Services 2 program".

Disneyland Is Source Of Legionnaire's Disease Outbreak
Disneyland has shut down two cooling towers after people who visited the Anaheim theme park came down with Legionnaires' disease. The towers were chemically treated to combat the problem, and there is no ongoing threat to guests' health, the Register reports.
The craft was made by the Sierra Nevada Corporation and was tested at NASA's Armstrong Flight Research Center in California.
The unmanned craft is created to launch atop a rocket and shuttle cargo and supplies to the International Space Station, and then return to land on a runway with experiments and samples from the space station.
It is about 9 meters long and is capable of transporting up to 5,500 kilos of cargo to the International Space Station.
The Dream Chaser is an autonomous, self-flying spacecraft, and this iteration will not carry any people. The Dream Chaser, however, which is meant to launch on top of an Atlas V rocket, glides down to Earth like a plane after reentering the atmosphere, landing horizontally on a runway. A company called SpaceDev resurrected the design, but after its founder left to form a space tourism company, SpaceDev was purchased by Sierra Nevada in 2008. "The testing will validate the aerodynamic properties, flight software and control system performance of the Dream Chaser".
