I well remember taking part (reluctantly: I was off-duty at the time, relaxing over a pint in the Residences, when some misbegotten oaf went round bashing on doors and coralling all of us who looked out to take part in the event) in one of those Major Incident rehearsals. At one point I had to escort a suspected #cervical spine to X-ray, the volunteer patient duly collared up and forbidden to move. We get into X-ray, which is staffed by thoroughly-pissed-off technicians - I think they'd been press-ganged too. One of them looks at the docket, says "Come on mate, help us" to the 'patient' while forcibly yanking his head forward to insert the plate. There was a great hiss from behind us where the observers stood, and one of them pipes up, "Congratulations, you've just killed this patient." The tech just glowered and muttered "So the fuck what" under his breath. I'm trying to keep a straight face.
