WHBM, I am old enough to have seen the Electra and Vanguard together at LHR and you are so right, the Elkectra wa smore like an oversized Viscount and of course didnt have the deep and wide fuselage of the Vanguard which was still a pretty big aricraft up against 707s and DC8s. The only thin about the Electra that was bigger was the smoke trail
its actually hard to look back and compare .'giant airliners ' from the 50s and 60s to something like a 777. A few years ago I saw a DC 6 at Blackbushe and it didnt dominate its surroundings like I thought . probably no bigger than ATR 72 or similar . Itw as great to see and hear it , perhaps the last time I will ever hear the music of 4 big radials
