The linked on "parasite fighters" says that they are part of "composite aircraft systems". Before this, I thought the aerospace company Scaled Composites was a reference to materials (like fiberglass etc). The more you know!
The 'Composites' in Scaled Composites is definitely a reference to the materials. From Burt Rutan's wikipedia page:
With his VariEze and Long-EZ designs, which first flew in 1975 and 1979 respectively, Rutan is responsible for helping popularize both the canard configuration and the use of moldless composite construction in the homebuilt aircraft industry.
