DennisK,
You seem to have had more to do with the Enstrom than you recall!
I rang my Dad yesterday to ask him to look out some pics of the Enstrom but he was out and while leaving a message with my Mum she recounted a story of her own relating to the Enstrom that might be of interest to you. Apparently my Dad brought a fellow Enstrom pilot home for lunch one day and said pilot repaid the good deed by taking my Mum and my younger sister for a flight in the Enstrom. My Mum was apparently so terrified that she spent the entire flight gripping the pilot's knee, much to my sister's embarassment!
I have checked the facts with my Dad and apparently the pilot in question was a certain DennisK! Surely you don't forget an incident like that in hurry?!
