In , famed ocean explorer Jacques Cousteau found the Britannic lying on its side feet below the surface of the Aegean. The cause of the explosion remains unknown, but many believe that the Britannic hit a mine. But if you see something that doesn't look right, click here to contact us! Thomas Edison announces his invention of the phonograph, a way to record and play back sound. Edison stumbled on one of his great inventions—the phonograph—while working on a way to record telephone communication at his laboratory in Menlo Park, New Jersey.
His work led him to Finding herself onstage as a result of pure chance after her name was drawn out of a hat, the Ewing, the character fans loved to hate. Legend holds that on November 21, , President Abraham Lincoln composes a letter to Lydia Bixby, a widow and mother of five men who had been killed in the Civil War.

National Security Council staff member Oliver North and his secretary, Fawn Hall, begin shredding documents that would have exposed their participation in a range of illegal activities regarding the sale of arms to Iran and the diversion of the proceeds to a rebel Nicaraguan On its sixth trip through the Aegean on November 21, to pick up wounded soldiers from the Middle East the Britannic hit a mine planted just one month earlier by a German U-boat. A breach in the hull and open portholes to ventilate hospital wards saw water pour in and the ship began to list to the starboard side, where water was gathering following the explosion to this flank.
In a desperate bid to save the lives of the people on-board, Captain Bartlett attempted to beach the Britannic in the shallow waters of nearby Kea. As he was desperately churning the propellers to this end, the medics were evacuating people. One of the improvements made to Britannic following the Titanic catastrophe was the ability to deploy lifeboats even when the vessel was severely listed.
This allowed them to put two lifeboats in the water to the port side as it was sinking during the captain's last-ditch manoeuvre. Unfortunately, they were deployed too soon and became tangled in the propellers. Two boats and their fleeing inhabitants were fatally diced in the spinning blades. The captain managed to cut off the engine before any more lives or boats were lost. On its sixth trip through the Aegean on November 21, to pick up wounded soldiers from the Middle East the Britannic hit a mine and sank.
Britannic was to be the largest vessel lost during The Great War. After completion in early , the outbreak of WWI put an end to her luxury liner plans pictured and the 48, tonne vessel was converted into a hospital ship for the Royal Navy before her maiden voyage.

As the name suggests, they emit virtually no excess gas. This is important for the next stage of exploration in the wreck.
Bubbles or pools of exhaled gases would disrupt the delicate marine ecology of the interior, speeding up the degradation of fragile wood panelling, for example. The depth is near the limit for even experienced technical divers and their time at the bottom is limited to 40 minutes or so. Even that short dive time on a gas mix of helium, oxygen and nitrogen requires a slow decompression of over five hours to reach the surface safely.
Oxygen levels are reduced in the mix breathed at depth to prevent the very real dangers of oxygen toxicity - the gas can trigger convulsions and deaths at increased pressures at depth. Nitrogen levels are also reduced relative to normal air and replaced with helium to avoid the dangers of nitrogen narcosis, a "rapture of the deep" that impairs judgement and incurs penalties in the divers' bodies as nitrogen bubbles form in the tissues.
These dangers are reduced by a long, slow ascent to the surface, stopping at precise depths and changing gas mixes until the divers are breathing air in the shallows. He has dived on the Britannic many times over four expeditions in , , and Kovacs explored the Titanic in with the History Channel and opted to visit the Britannic in to see if they could learn something about the Titanic by looking at the differences in construction and the changes made to her sister ship.
Unlike the Titanic she is almost intact; she is one of my favourite long-term projects," he says. It's the best in the world in my view, just brilliantly designed and perfectly equipped for this kind of work. One of the big advantages for the divers and image makers in was the presence of a wet bell.
This is a platform with a breathable air bubble supplied with hot water and communications from the surface. Plus it's easy to keep hydrated and to be able to eat and listen to our iPods during the long hours of decompression.
The only thing missing is a cup of hot tea," he jokes. To get around this huge wreck in the limited time - only 45 minutes - that the divers have at depth, they use underwater scooters. Even with rigorous safety measures in place, the sea is still unpredictable, especially at these depths. Britannic claimed the life of world-renowned technical diver Carl Spencer in and Kovacs says that it's not uncommon to hear the explosions of illegal fishermen nearby.
Kovacs' holy grail for this wreck is a rivet-accurate blended acoustic and optical model of the entire exterior yielding a hugely accurate picture of the bulkheads. What this means in practice is a 3D volumetric model. The acoustic images have been taken with multibeam and side-scan sonar from the Perseo ROV and these will be overlaid with the optical results from the divers. On land, this is not such a difficult proposition, but underwater there is a classic mosaicking problem. It is impossible to go super-wide to gain the entire perspective - underwater visibility prevents that on a structure of this scale.
The team must first build an acoustic model to ground-truth the optics. While owner Simon Mills has been offered the opportunity to dive to the wreck, he has declined "I am a recreational diver," he says.
