Because in 1989 I was a 19 year old spooty faced new co-pilot on the S61 in Aberdeen!
Ah, the years roll back...............
I remember OG had a Flight Director too. I was also involved in CAA sponsored and recorded trials at Prestwick in August 1980 with OG flying it down to 50' Rad Alt behind the screens and clocking up 12 ILS's in a day!!!
