After a dayslong, massive search for a Titanic-bound submersible that captured international attention, US authorities announced the vessel had suffered a “catastrophic implosion” – and new information from a US Navy source helps shed light on when that disaster may have unfolded.
All five people aboard the submersible, known as the “Titan,” were killed, the US Coast Guard said in a Thursday news conference. The tail cone and other debris from the missing submersible were found by a remotely operated vehicle about 1,600 feet from the bow of the Titanic, which rests about 13,000 feet deep in the North Atlantic Ocean.
“The debris is consistent with a catastrophic implosion of the vessel,” US Coast Guard Rear Adm. John Mauger, the First Coast Guard District commander, told reporters.

Five people were detained for trying to export a kilogram of radioactive caesium-137 to use it to the detriment of Russian interests during a special operation, the Russian Federal Security Service (FSB) said.
The Russian Federal Security Service said that those suspected of trying to smuggle caesium-137 out of the country to discredit Russia had been arrested and are confessing. A case was opened on the illegal handling and smuggling of radioactive substances.
Caesium-137 is a radioactive isotope that is commonly used in medical and industrial applications, in addition to peaceful uses, caesium could be used to make weapons of mass destruction. Due to its long half-life and high energy radiation, caesium-137 poses a significant hazard to human health and the environment.
