Train hard yes. However if this was training being so close to members of the public so as to put them at risk is not acceptable. Go do it in Otterburn. Any dash cam in general use contains a wide angle lens. This is clearly the case therefore the aircraft and rotor blades will be closer than they look.... and being able to hear it pass on the audio backs this up. I wonder how the cyclist who was overtaken at the start of the clip felt a few seconds later. Might downwash have blown him across a greasy wet road into the oncoming car.... just a bit of perspective. Of course if it was for tasking then fair enough. Can’t imagine it is though. Being a twin IFR cab though a high level transit of the lakes might be best. All just food for thought.
