An exciting development for rescue services.
The UK's Great North Air Ambulance Service has successfully carried out a test flight, for a jet suit that would power medics to a mountain top in 90 seconds.
Run in the Lake District, Great North director of operations Andy Mawson told Mike Hosking his team's ecstatic with the results.
"It was incredible to see the jet suit zoom up the side of a mountain to a simulated casualty."
Mawson says the test went better than expected.
He says the jet suits would allow medics to safely cover steep ground quickly.
