there was a thread - not sure here or elsewhere- about 5 years ago on a fatal accident in the west country, cornwall i think.
at about that time, as a newly qualified PPL i was blown sideways by a metre or so in the flare, i believe by the wash from a large helicoptor at a taxiway holding point, which was close to my aiming point. no damage done, but valuable lesson - aim further down - land long - keep well away from those blades.
