Nicky Gray sent me this (https://www.theguardian.com/jet-suit-paramedic-takes-lake-district-test-flight) – an emergency jet suit paramedic defying gravity, zipping across the Langdale Pikes in search of a party of walkers simulating a casualty scenario. Mission accomplished within minutes, not the normal hours.
A tip of the hat to inventor Richard Browning, the Great North Air Ambulance Service, Gravity Industries (and Nicky Gray for sharing).
