Hi ChristiaanJ,
Bien-sur, Sud-Est used the Comet 1 nose section for the early Carravelles. (Round about that time, the Comet 1s were permanently grounded, so perhaps there were plenty of them going cheap?) But the later Caravelles had a modified version, as can be seen in Airmann's link. I think the Comet Mk 3/4 may also have had deeper windshields than the Comet 1/2.
Considering the stunning price of the flat windshields (ignoring the side windows) on large airliners - with anti-misting elements inside the inner lamination, and anti-icing/anti-bird gold film inside the outer lamination - these large curved windshields must cost an absolute fortune. Perhaps the convex shape improves bird resistance?
I wonder how they avoid optical distortion, particularly if they are mounted less vertically than traditional designs. Any B787 pilots out there to comment?
