XRS-2200 Linear Aerospike Engine Test fire at NASA Stennis Space Center (SSC)

This engine was designed to be modular so if necessary, it could be stacked end to end. It was originally designed to power the long since cancelled X-33 Venture Star. I knew I had seen a video of this before but I couldn't find it anywhere. By pure chance I found it through a dead hotlink to a Marshall Space Flight Center (MSFC) news release. I believe this is 80% of max thrust.
