Another insane article:
By JUAN CARLOS LLORCA, Associated Press Writer
GUATEMALA CITY, Guatemala - A 330-foot-deep sinkhole killed at least two teenagers as it swallowed about a dozen homes early Friday and forced the evacuation of nearly 1,000 people in a crowded Guatemala City neighborhood. Officials blamed the sinkhole on recent rains and an underground sewage flow from a ruptured main.
The pit emitted foul odors, loud noises and tremors, shaking the surrounding ground. A rush of water could be heard from its depths, and authorities feared it could widen or others could open up.
Rescue operations were on hold until a firefighter, suspended from a cable, could take video and photos above the hole and officials could use the documentation to decide how to proceed.
The dead were identified as Irma and David Soyos, emergency spokesman Juan Carlos Bolanos said. Their bodies were found near the sinkhole, floating in a river of sewage.
Their father, Domingo, was still missing, according to disaster coordinator Hugo Hernandez.

World's Tallest Bridge
This is seriously mind blowing:
Construction of the Millau Bridge in France
The Millau bridge over the River Tarn in the Massif Central mountains is more than 300m (984ft) high - taller even than the Eiffel Tower. With its concrete and steel pillars soaring high above the morning fog in the Tarn Valley, the construction makes a spectacular sight.
Construction began in October 2001 and was intended to take three years, but dragged even longer because of weather conditions. The bridge was built by Eiffage, the same company that built the Eiffel Tower.
A complicated system of hydraulic rams was used to slide the vast bridge deck into place. It was provided by Enerpac Hydraulic Systems - the company which also "lifted" Golden Gate Bridge off its foundation for better cushioning against earthquakes. Here is a diagram of pushing the bridge's deck:
The deck was pushed in two sections from both sides of the valley. Each push cycle lasted 4 minutes and moved the deck section 600mm a time.
From both sides of the valley the metal sections of the bridge are assembled, lifted slightly and then in an elaborate manoeuvre pushed into place on each of the seven supporting pillars. The architect, Norman Foster, said the bridge was designed to have the "delicacy of a butterfly"
