UPS Inc. is taking its package delivery empire to new heights—quite literally. Earlier this year, the Atlanta-based company launched the first ongoing, revenue-producing drone flights in the United States with its partner Matternet and now operates multiple daily deliveries of medical samples by drone on the WakeMed hospital campus in Raleigh, North Carolina.

In addition, UPS announced in April its participation in a partnership to expand life-saving drone service into Ghana, providing blood and vaccines to hard-to-reach clinics throughout the African country.
