Savoia,
Norman Bailey's company (
The Manchester Helicopter Centre) is based at Barton Airfield (EGCB) - I believe it is now run by his son and they still operate a couple of Enstroms. I was told that in days gone by, a number of Enstroms were sold to MHC students, so I suspect that is why the name/company keeps cropping up.
I was taught to fly by one of the Bailey's former instructors who had an endless array of fascinating stories surrounding the helicopter industry in the 1970s/1980s! It was this same instructor who had connections to the DofW's pilot/helicopters as previously discussed in this thread.
Norman Bailey has authored three books about helicopter flying (entitled "The Helicopter Pilot's Manual" Vol I/II/III) - these are concise tomes but are filled with useful information. They certainly provided a useful starting point on the basic principles of flight.
Sorry not to be able to provide any significant trivia/nostalgia - I am sure others will have much more information to share...
