Two Wings, Many Prayers (2013)

Two friends with a love for aviation and adventure decide to design and build their own tiny aircraft. They also want to attempt to fly the little single engine, two-seater around the world. Technically, attempting to fly around the world in such an aircraft may just be possible, and without doubt it would be a high-risk endeavor that most pilots would classify as insanity. James Pitman and Mike Blyth aren't aeronautical engineers, they're not even mechanics. But they have seen a gap in the market for an affordable, reliable light aircraft and decide to go for it, hoping to make the deadline for Oshkosh, the world's greatest air show. With the clock ticking down, they rush to complete the build of the plucky little plane that will become known as The Sling.
