Sad event, hope Family taken care of.
During my ramp training 1968, we would have to duck under the fuselage of the Viscount to pull the GPU plug after engine starts, Dart noise was enough warning, but my colleague lost an eye from ducking into an antenna.
Doing my on job engine run F27, I asked where is the pre-start check for anti collision light, reply none fitted on this ship; as name states 'anti collision' Not anti ingestion.
1978 during an engine, B737-200, run the mechanic doing the trim adjustment got sucked in, engine surged and Engineer immediately shut it down, mechanic lost fingers on one hand, fixed inlet guide vanes saved him from more loss.
Noticed on recent flight on ATR72 the #2 engine was S/D first and prop brake assist, perhaps to allow GPU connect, the pax and bag loading was #1 side.
