Pretty cool! I’ve actually been to the site where the Hindenburg went up in flames. There’s a small museum there with pieces of the actual blimp in it, including a tiny piece of the Nazi flag that was painted on the tail portion. Felt pretty odd for me to see that in person.

Mooring to the top of tall buildings didn’t generally work well in practice

Maybe they kept it around in hope of making it a flying saucer dock, as in old Popular Mechanics cover art.

Chicago has one, but it’s never been used
