Beyond Blue Sky is a 93-minute documentary exploring how from 2001 to 2004, a small team of engineers in California’s Mojave Desert built a simulator, a mothership and a rocket-propelled glider that test pilots Mike Melvill and Brian Binnie flew to space three times. It was a supersonic physics experiment that thankfully ended in aerospace immortality for the corner-cutting geniuses, who operated on a razor’s edge to prove to the world it was possible to have a low-cost, privately financed, manned space program.
