That Connie
That Connie was probably G-ARXE which was the last to carry the Skyways of London livery. I think it was a L749, the rest being L049s or L149s (I say "I think" - it was 50 years and 2 strokes ago), those other 6 all wore Euravia colours.
I was an ATCA at Luton from 4/1964 to 3/1965 when I went to EMA when it opened. My claim to fame was that I was on duty when G-ANBB, the first of the Britannias, was delivered and the airline changed it's name.
