I'll be able to claim I saw the Good Year blimp once in my life on my way back home, driving through Akron OH.
I once saw the Good Year Blimp up close and personal, It almost crashed on top of me.
I had walked around the block one fine sunny day and paused at the corner when I heard a sound like chainsaws running full out.
I looked up and thought at first it was a balloon low overhead, because it was pointed straight down right above me with engines straining trying to right itself.
They got it under control and the engines stopped. the Blimp then righted itself and drifted away gaining altitude as it went.
I watched it for quite awhile.
As it drifted the sun was glinting off what looked like a long cable hanging down, but I suspect it was a stream of water from ballast tanks, if that is what they use.
Years later I read of two serious accidents caused by glitches in the ballast system causing these blimps to suddenly go nose down.
There's a large athletic field nearby. Perhaps they were trying for an emergency landing but couldn't get lined up on it before they figured out how to regain attitude control.
