    Added the original paper by Whitney on fiber bundles.

    I have removed the sentence

    One may say that ’fibre bundles are fibrations’ by the Milnor slide trick.

    from the Idea-section, and instead added a section Properties – Relation to fibrations (here) with statement that fiber bundles are fibrations, and a warning that the converse fails.

    • (edited May 9th 2023)

    Added (here) my best attempt at replacing the “(diagram to come)” text that’s been “to come” for 14 years. Comments and improvements welcome, in particular:

    • I’m not sure about how to render isomorphisms, I just went with headless arrows.
    • I’m not sure if the direction of the transition morphisms as written here matches the usual one in the literature.

    Thanks, looks good.

    I’m not sure about how to render isomorphisms, I just went with headless arrows.

    I would certainly want to keep the arrow head on any isomorphism: The direction matters, even if there is an inverse.

    In tikzcd I find a good way to code isos is by “\ar[..., "\sim"{sloped}]”.
