Being engineers, we’ve constructed these manifolds and put them to use before understanding them. Also our point of view is extrinsic rather than intrinsic—seemingly the opposite of most of the literature on ruled manifolds (which to be candid, we are having considerable difficulty assimilating). For us, ruled manifolds are higher-dimensional (Kahler) analogs of ruled surfaces.

Now as it happens, I’ll be spending a few days in Vegas this coming week with my Marine Sgt. son & need something that can be read poolside with enjoyment.
