It was something I had never considered but it is wild to think about. I believe it was Vaclav Smil that highlighted it to me. On its longest trip an A380(I think?) takes off weighing 400 tons and lands weighing 200 tons. That kind of thing is just cool to ponder.

I realized while working on heavy transport aircraft that they their weight can be (very roughly) 1/3 aircraft, 1/3 fuel, and 1/3 cargo, and being struck by how different these proportions are from the family sedan.

It is literally insane how much oil there is. Planes use i think less than 10% of world oil consumption.

Rockets reaching orbit are an interesting example too.
