In the series premiere, Mighty Planes joins the crew of the worlds only flying eye hospital for their most challenging mission to date. Orbis travels tirelessly around the globe, offering patients in developing countries precious sight-saving treatments. On the outside, it's a regular DC-10. On the inside, it has been stripped and re-designed to house a state-of-the-art ophthalmic hospital complete with an operating room, a laser treatment facility and a high-tech classroom from which student doctors in host countries can watch surgeries live on 54 video screens.
