The Vickers Viscount
The first fare paying passenger flight, a turbine first, took place on 29th July 1950. The fiftieth aniversary did not attract the same publicity as the Comet but then the Viscount went on to be a commercial success.
I was wondering if there are any plans to celebrate the fiftieth aniversary of the first production version, the 701, the first fleet operation as oposed to the prototype carrying passengers prior to being returned to Vickers?
The first production aircraft flight was by BEA, London to Cyprus with stops in Rome and Athens on April 18th 1953.
