World Anti-Doping Agency data, and played a key role in

Within moments she then receives a text message from the sub saying it had dropped two weights, which seems to have led her to mistakenly think the dive was proceeding as expected.The USCG says the noise was in fact the sound of Titan imploding. However, the text message, which must have been sent just before the sub failed, took longer to reach the ship than the sound of the implosion.

All five people on board Titan died instantly.Prior to the fatal dive, warnings had been raised by deep sea experts and some former Oceangate employees about Titan's design. One described it as.

Titan had never undergone an independent safety assessment, known as certification, and a key concern was that its hull - the main body of the sub where the passengers sat - was made of layers of carbon fibre mixed with resin.The USCG says it has now identified the moment the hull started to fail.

Carbon fibre is a highly unusual material for a deep sea submersible because it is unreliable under pressure. A known problem is that the layers of carbon fibre can separate, a process called delamination.

The USCG believes that the carbon fibre layers of the hull started to break apart during a dive to the Titanic, which took place a year before the disaster - the 80th dive that Titan had made.Eventually he was admitted to the "normal" prison where inmates had to bunk together in crowded cells and where the lights were never turned off.

You also ate in the same room, he said.According to Radalj, African and Pakistani prisoners made up the largest groups in the facility, but there were also men being held from Afghanistan, Britain, the US, Latin America, North Korea and Taiwan. Most of them had been convicted for acting as drug mules.

Radalj said that prisoners were regularly subjected to forms of what he described as psychological torture.One of these was the "good behaviour points system" which was a way – at least in theory – to reduce your sentence.
