1891 Proposal for a bullet ride dropped from the Eiffel Tower

On his science book blog John Ptak posted an entry entitled, "Dreaming of the 10-Ton Eiffel Tower Bullet, 1891," about a proposed fun ride in which people would sit inside a giant bullet and freefall from the top of the Eiffel Tower into a pool of water.

[Okay, so the thing would hit at 178mph or so, and, assuming that the whole thing didn't get completely crushed on impact, I'm not so sure that 200' of depth is very much wiggle room for the thing to come to a halt (if it didn't deform). Also it would have to not have any wind deflection so as to not veer off its perfect entry into the water.  And so on.  Calculating the force of impact is difficult without knowing how far down the bullet would go, but hitting the water at 80 m/s and stopping at 30 meters would yield something like 28,600,000 KE and 1,274,000 N. There are lots of problems…]

The thing is, though, the thing that made this so appealing, is that for the 20-francs that get a person a seat in the bullet, that they would each get to go twice as fast as any human had ever traveled before ( 65 miles per hour was about the speed of the fastest train constructed).
