500 fan, that Hiller was sold to a Mr Ken Besson I believe and had been owned by the US ambassodor to Ireland (name?) who was selling his personal hiller as he returned to the states. I recall seeing it in Rosslare when I was a wee lad, I believe it was in a blue colour scheme. If I recall correclt Ken Besson if I have his first name right formed Irish Helicopters with that hiller but I am open to correction on that. I also seem to remember that the oil crisis put him out of the picture and Aer Lingus took over Irish Helicopters as a subsidiary for a number of years.
