Add this to the list of things we are amazed by: Facebook has built a plane that will deliver internet connectivity to remote areas via lasers.
The plane is constructed of foam wrapped in carbon fiber, and has a wingspan wider than a Boeing 747, but it weighs less than a Prius.
The plane will fly crazy high in the atmosphere, above commercial airline flights and above the cloud level, and will be powered by an array of solar panels on top of the plane.
