Impossible Aerospace is a US startup that manufactures an all-electric, high-endurance multirotor drone called US-1. The drone platform is marketed mainly towards first responders—law enforcement, firefighters, and more. US-1 boasts a flight time of 78 minutes on a total vehicle weight of 17 pounds. Keenan Johnson, one of Impossible Aerospace's co-founders, joined me on this podcast that was recorded at AUVSI's 2019 XPONENTIAL Conference in Chicago, IL.
