In fact Euravia bought most of the Skyways operation, I think in 1963, for the token sum of 1 GBP. This included the Skyways' Connies and an Avro York freighter. I believe it also included the maintenance operation. Syways Coach Air operation with Avro 748s was not included in the deal.
Euravia itself was formed in 1962 by J.E.D. Williams and Ted Langton. First commercial flight was 5 May 1962. It became Britannia in 1964 when the whole concept of Europe went a bit pear shaped in the UK as Mr de Gaulle had famously said "Non!" to UK entry into the common market. Surprisingly, the name Britannia had not been taken up by any other airline and Euravia was starting to requip with ex-BOAC Britannia 100 series aircraft.
