Huh?  At least by the time of the Comet 1 crashes, Comet 1s had de
Havilland Ghost engines (although the airlines wanted the more powerful
RR engines).

I don't believe the preferred engies were Conways -- they didn't turn up
until the 707 era.  The RR engines proposed for for the Comet 1 were pure
turbojets like the Ghosts; Conways are fans.

I'm not sure about the Comet 4; they may have had Conways.
