A video of a Coca-Cola being instantly crushed by water pressure gives an idea of what likely happened to the destroyed Titan submersible that claimed five lives. The pressure chamber on board OceanGate's 22-ft vessel suffered a'catastrophic implosion', authorities revealed on Thursday, and the men aboard tragically perished. The implosion would have been caused by a sudden change from low to high pressure inside the sub, possibly triggered by a defect in the sub's walls. Experts say the crew and passengers would have been crushed within a fraction of a millisecond, an event so fast it would have been over before they realized what was happening and so violent it's unlikely to leave anything but a mist of human remains. A video posted by James Hambley, a YouTuber who goes by the alias Barded Science Guy, shows a similar implosion happening to a Coke can.

Inside the sealed vehicle are OceanGate CEO Stockton Rush; British businessman turned adventurer Hamish Harding; father-and-son Shahzada and Suleman Dawood, who are members of one of Pakistan's wealthiest families; and Paul-Henry Nargeolet, a former French navy officer and leading Titanic expert. The U.S. Coast Guard headed a unified command that involved commercial assets, research vehicles and military counterparts from Canada, France and the United Kingdom.

Fox News correspondent Molly Line has more on the search to rescue the five individuals on the Titanic voyage on'Special Report.' BOSTON – Three new vessels arrived "on-scene" in the Atlantic Ocean Wednesday morning to join search and rescue efforts for the missing OceanGate Titan sub as the estimated oxygen supply on board continues to dwindle. The U.S. Coast Guard said the new vessels bring additional tools to scan the ocean floor as they race against the clock to save the five people onboard: OceanGate CEO Stockton Rush, British businessman Hamish Harding, father-and-son Shahzada and Suleman Dawood, who are members of one of Pakistan's wealthiest families, and Paul-Henry Nargeolet, a former French navy officer and leading Titanic expert. "The John Cabot has side-scanning sonar capabilities and is conducting search patterns alongside the Skandi Vinland and the Atlantic Merlin," the Coast Guard said. The John Cabot is a Canadian coast guard vessel, the Atlantic Merlin is a Canadian remotely operated vehicle (ROV), and the Skandi Vinland is a commercial ROV, authorities said.

A team of researchers have developed a new algorithm that could help search and rescue teams locate people lost at sea using ocean currents, wind speed, and wave direction. The project was a joint effort from scientists at MIT, the Swiss Federal Institute of Technology (ETH), the Woods Hole Oceanographic Institution (WHOI), and Virginia Tech, who tested their method using human manikins in the ocean off the coast of Martha's Vineyard. Unlike current search and rescue models--which also use data about ocean currents and wind to calculate the likely location of a missing person by simulating one single linear path--the team's new system is focused on identifying multiple points of'attraction' in the ocean, which can sometimes change dramatically over time. Using a system they called Transient Attracting Profiles (TRAPS), the team tracks these attraction points, which they behave like'moving magnets' pulling people in the water toward them. Instead of mapping out a single, linear path, the TRAPS model identifies many different attraction points, or'traps,' in the ocean that will likely have pulled a person in multiple directions as they drift through the waters.

Hoax callers are a special kind of jerk. At best they can cause their targets emotional distress. At worst they can cause or incite property destruction and even divert scarce resources from real emergencies where they are needed to save lives. Technology can sometimes be applied to catch the criminal. Doing so casts technology specialists in the detective role by letting them trace calls to find their origins.
