@isaackuo @Infoseepage @nyrath No, it's for use in the Lake District, which is compact but crinkle-cut. There are roads, but hill walkers regularly get into trouble within half a mile of the road and it takes rescue climbers ages to get to them. The idea is to keep a jet pack in the back of an ambulance in order to get a first-responder the last half-mile over broken ground to a casualty as fast as possible to stabilize them for portage or airlift.
