Worked for BMA at MME when we did four LHR rotations a day with the Viscount. Lovely aircraft had several jolleys to LHR, OST and once did a day long "W" MME-JER-CDD-JER-MME. Seemed to fly a lot with Joe Sharps and Jim Smee.
A good book for a really in depth development story is The Handbook of the Vickers Viscount. Can't remember the author but it's a very good read.
