Coaster Zone: The Rollercoaster Social Network

With a sheer drop of 415ft - higher than the Statue of Liberty - and travelling at speeds of 90mph, a new record-breaking ride will not be for the faint-hearted.
A New Jersey company is planning to build the 41-story drop ride, making it the world’s tallest.
Six Flags Great Adventure says Zumanjaro: Drop of Doom will hoist riders 415 feet in the air and drop them back to the ground at 90 mph.
The stomach-churning attraction will be attached to what is itself the world’s tallest roller coaster, Kingda Ka in Jackson, New Jersey.

That looks amazing. 90mph on a drop tower will be so fun.

Apparantly, on a clear day, from the top you'll be able to see the skyline of Philidelphia, 52 miles away!

The problem I see with adding a drop towers to a coaster is that the coaster structure was only ever designed to support the coaster, not to support anything else a park wishes to add to it, I also don't see it very practical as normally you aren't allowed to go near the bottom section of the top hat in case anything falls of from a rider like a coin or anything in a pocket of a rider.

That sounds amazing! I love drop towers and views of over 52 miles will be awesome.
