Wing and Loon, two projects from Alphabet’s “moonshot lab,” have officially taken flight.

Wing, which delivers packages with autonomous drones, and Loon, which delivers internet through weather balloons, are the latest companies to spin out of X, Alphabet’s home for projects that fall outside of Google’s traditional advertising, software, and hardware businesses. Former graduates of the lab include the self-driving car company Waymo, and the cybersecurity company Chronicle.
