This is basic stuff for the majority of you but the emergency services do not move until instructed to do so by ATC; little point in charging across the active and causing further dramas really.
Fire attend first (when cleared), ensure scene safety then call for ambulance attendance if necessary. The ambo crew then seek clearance also if not already given.
Time does seem to drag for the lay person in an emergency; I'm told there is nothing worse than waiting for an ambulance when you need one!
It's been a couple of years since I've covered Duxford but that's how it was last time I was there.
Cambs Fire & Rescue are already in attendance on the site alongside Duxford Fire Service, snapping up some overtime whilst having a pleasant day out (like myself) no doubt.
