My friend is the founder, working in Ann Arbor with an amazing group of aeronautical and electrical engineers, medical researchers, and others. They're building hardened VTOL drones to take medical supplies, samples, tests, back and forth from hospitals to rural India. They have a great team and deep relationships with the NGO and health sectors in India.
