You say that the Halifax is no more. Has it been scrapped or has the museum closed?
I remember graduating from Oakington, and being told that I had been posted to Hercules – 2 on each wing.
1200 hours later I never had a failure, but the unit had a few ‘stop’. I seem to remember it was 1000 hours between overhaul. A bit different from the RB211!
I saw a Hercules running on a Sunday morning, at a gathering in Melton Mowbray a couple of years ago. Magnificent, although the nearest and dearest plus god children not really impressed. A shame it was not dark and you couldn't see the 3 feet of flame coming out of the exhaust stubs.
I just kept thinking about the 50 gallons of 100/130 it was burning every hour, and how could he afford to fire it up.
