" the UCADA official was attempting to board the helicopter from the wrong side despite the pilot’s instructions" not a selfie.
That seems one of the common passenger death causes - tail rotor or walking into a propeller. I looked for the other recent one that a passenger supposedly ran from the building and into the tail rotor, but appeared to be the same sort of case. I suppose that staying under spinning main rotor blades is unnerving and going around the tail gives the appearance of greater safety than scooting around the nose.
