Project MUSTARD (Multi-Unit Space Transport And Recovery Device) or MUSTARD, was a 1960’s design concept from the British Aircraft Corporation (BAC) able to place payloads of up to 5000lb (2,300 kg) into low earth orbit and stood some 118 feet  (36 m) tall. The unique feature of the spaceplane was that each stage was piloted and so able to land on a runway and be used again. The project was finally cancelled however in 1970.

The build is in three parts, the launch pad , launch tower and spaceplane. I would recommend that the launch pad is rezzed and positioned first followed by the launch tower and finally the spaceplane.
