Experimental spaceplane engine completes multiple test firings

To achieve this, the unmanned, autonomous Phantom Express lifts off vertically from a launch pad. After reaching hypersonic velocity, it goes into a sub-orbital trajectory to the edge of space, where it releases a piggyback second stage to send the payload into orbit. The key to the spaceplane is an updated version of the AR-22 engine. It burns a mixture of liquid hydrogen and liquid oxygen to produce over 375,000 lb of thrust for at least 100 seconds.
