And that is why researchers are proposing we bring back Zeppelins! Zeppelins that are 10x as long as the Empire State Tower is tall, to be exact. Way better for the environment, can be operated autonomously, and cheap to produce.

If I take hanniabu's numbers, that ends up with 8000 ft. zeppelins--the length of airport runways. That's probably not going to be operationally viable: going by the space the largest seaports take up today, you have space to berth only a few of them--maybe 5 at best--at the very largest of them. There's therefore going to be very poor operational flexibility for choosing routes, and with the sheer size and capacity, multi-destination itineraries are going to struggle with long dwell times to partially load/unload them.

You figures are incorrect, this is taken directly from the linked article:

> As proposed in a recent scientific paper, the new airships would be 10 times bigger than the 800-foot Hindenburg — more than five times as long as the Empire State Building is tall
