Kingda Ka, the world's tallest roller coaster, has been reduced to a pile of rubble by an implosion.
The Ocean County Prosecutor's Office said the implosion was expected to happen between 9 a.m. and 10 a.m. However, the coaster was brought down just before 7 a.m.

The proecutor's office warned that "the noises may be startling, but please don't be alarmed."
Chopper 6 was overhead the remains of the thrill ride that is now just a pile of mangled steel.
Now, crews will work to remove what is left ahead of plans for a new roller coaster.
The ride propelled passengers up a 456-foot-tall tower at speeds of 128 mph.
Kingda Ka delivered more than 12 million rides since 2005, Six Flags said.
