It was the nose and cockpit profile that was so right looks wise, something you see in the new Boeing Dreamliner, that comes close to it. Loved working on them for many years...
I think the BOAC decision to buy the 707 instead of more put the nail in its coffin, indeed some of the work done on it allowed it to support the 707 for the US market by enabling it to carry a spare engine under the wing for the Conway powered 707...... The last one of which was broken up at Cosford recently
Here is Lufthansa buying a Connie and funding a hangar in the USA to restore her to flying condition as well as operating a Ju52 and BA cannot even dredge up funding to look after their historical ground based Aircraft at Cosford, preferring to scrap the lot.......... says something does it not!
