My first ever flight on a Viscount was not a BAF one, I think it belonged to North East and was G-AOYL from London Heathrow to Leeds Bradford in Feb 1975.
My one and only experience of a BAF Herald. I was expecting a Gulf Air F27 from Bahrain to Dhahran. I got into this thing and realised it was not a F27 and the charming stewardess told me it was a Handley Page Herald and had just arrived from England and was on a wet lease.
