Tonight CNN will broadcast "Cruise to Disaster," a documentary into the Costa Concordia disaster. Here is the lead in to the CNN special program:

"What we found will be unsettling for anyone who has taken or is thinking of taking a cruise: allegations of inadequate safety briefings and chaos in the minutes after the collision; a captain who failed to sound a general alarm for almost an hour, meaning vital, lifesaving assemblies at lifeboat stations did not take place; and a crew that felt unable to act without clear orders from their captain.

In some cases, lifeboats were not able to be launched because by the time the general alarm finally sounded at 10:48 p.m., the ship was leaning over too far to allow the lifeboats to launch. Thirty-two people died in the Concordia disaster.

We learned that 6,000 tons of water entered the Concordia in just 20 minutes. For a ship three times the weight of the Titanic, it was fatal. Almost immediately, key equipment in the engine room was knocked out. The ship’s backup generators were flooded.

Computers that monitor the ship’s stability were also compromised. CNN’s documentary team obtained remarkable footage from the ship’s bridge that revealed Captain Francesco Schettino grappling with a situation that was already out of control. His ship had a hole below the waterline the width of a football field.

We also found compelling evidence that Schettino’s decision to "salute" the island of Giglio by sailing perilously close caused the accident, but also that this wasn’t the first time the Costa Concordia had sailed within a few hundred yards of the rocks.

Schettino is still awaiting trial on multiple charges of manslaughter, causing a shipwreck and abandoning ship. Schettino escaped the ship on a lifeboat while the ship was capsizing. A transcript of his tense exchange with Port Authority officials can be read here, including their order to him to "Get on board, damn it!"

Here is the video introduction to the program tonight which airs at 8:00 PM EST:
