Here's Coney Island through the decades.
This one from the turn of the century has some flats from that era, Shoot the Chutes and the Steeplechase.

This Fatty Arbuckle comedy from the following decade has the Witching Waves (5:40) and better Shoot the Chutes (9:35) footage.

This one from 1940 shows some great flat rides as well as footage of Thunderbolt, Cyclone, Tornado and Mile Sky Chaser, but not the Bobsleds.

Here's a documentary from a dozen years later with more flats, the Virginia Reel, Cyclone, Thunderbolt, Flying Turns and the Bobsleds (but only for a couple of seconds).

This one is from the 1970s and shows how the place became a dump, but it does have some cool footage of Astroland and on-ride footage of Thunderbolt before it closed.

Although this one doesn't have much Coney Island footage, it does give you a good idea of what the place was like in the '80s.

And he did film their ride on Cyclone.

The only thing I could find from the 1990's.

Finally this one is Charles Denson's 2002 climb to the top of the Parachute Jump (after it was renovated).

And this hour long documentary from 1990 is simply amazing! The complete history of Coney Island through 1967 when Steeplechase Park closed.

FYI - I moved to New York City in 1981 and have been to Coney Island every year since then.
