One bit of caravelle trivia was the french fitting one out with cameras and in clear weather on trips eastwards straying off the airways to snap pictures of interesting features.....nothing the other side did not do of course. I think Paris Match (of all unlikely mags) might even have run an article on this (much later of course). The other unlikely fact I remember was Sterling (in jet vicar days) using them on transatlantic passenger flights, probably via Iceland (so I suppose not that different from Wow today). Either way I have always had a soft spot for the caravelle.
