Logistics startup Zipline has flown more than 38 million miles with its autonomous electric delivery drones since the company was founded in 2014. Zipline put its first fleet to work in Rwanda, delivering blood and other health supplies to clinics and hospitals. Since then, the Silicon Valley startup has expanded its service in six other countries, with limited delivery service and distribution centers in three states.

On Wednesday, Zipline showed off its next-generation aircraft, which it hopes will make rapid aerial deliveries an everyday convenience for customers throughout the U.S., even in densely populated urban areas.
