I was walking in the Langdale area the day they went up the Band and some walkers told me that there was a man going to jet suit up Harrison Stickle - they must have been misinformed. I later spotted the orange flare going off on the Band, exactly as in the video, and the helicopter hovering around, but no jet suit unfortunately - I was too far away.
As to whether this is the future, doubt it. Weather bound to be a big factor.
