In a series of unusually candid remarks, the US general in charge of the nation's nuclear arsenal has issued a stark warning that Russia and China are "aggressively" developing new high-speed, or hypersonic, weapons that the US currently has no defense against.The weapons might not be operational for several years, but Gen. John Hyten, the four-star head of US Strategic Command, is warning that changes to missile defenses are urgently needed or the US will be unable to detect them when they are operational."China has tested hypersonic capabilities. Russia has tested. We have as well. Hypersonic capabilities are a significant challenge," Hyten told CNN in an exclusive interview. "We are going to need a different set of sensors in order to see the hypersonic threats. Our adversaries know that."Hyten and other military officials say the current generation of missile detecting satellites and radars won't be enough to detect these new generation weapons. Hypersonic is generally defined as a speed of Mach 5 or over 3,806 miles per hour."We've watched them test those capabilities," Hyten told Congress last week. But with unusual public candor about potential US military shortfalls, he acknowledged "we don't have any defense that could deny the employment of such a weapon against us, so our response would be our deterrent force, which would be the triad and the nuclear capabilities that we have to respond to such a threat."Hypersonic missiles fly into space after launch, but then come down and fly at high speeds on a flight path similar to an airplane. Their lower trajectory make them more difficult for US missile defense satellites and radars to detect. Russia has openly stated it is developing high-speed air-launched missiles as well as underwater hypersonic drones.The Pentagon is currently writing a review of its missile defenses to help determine what new capabilities might be needed to deal with new classes of attack weapons. Hyten gave Congress a hint of what may be in that review stating "the first thing we need is better sensor capability, better tracking capabilities to make sure we can characterize and then respond to that threat."He also called for improved US warheads, essentially "better kill vehicles on the top of our interceptors so that those kill vehicles become more and more lethal." The Pentagon is also working on concepts for interceptor missiles that repel a barrage of enemy attack missiles. Current US missile defenses are designed to only shoot down a small number of enemy missiles.The US focus has largely been to work on hypersonic technologies across the board. But Russia is now well into testing some of its systems. Earlier this month Russia showed video of what the Kremlin said was an air-launched hypersonic ballistic missile.When asked how far along the Russian hypersonic program is, Hyten told CNN, "I don't want to put a who's winning the race, I'll just say there is a race."When asked how soon it could be before the Russians have an operational hypersonic weapon that could reach the US, Hyten said, "It's similar to the North Korea problem. If you continue to pursue that technology, you will get there. And the Russians will get there, the Chinese will get there and we'll get there -- and we'll have to figure out how to deal with that." 3323

Hundreds of passengers on an Amtrak train that became disconnected will have quite a story to tell around the Thanksgiving table.The Montreal to New York train was traveling near Albany, New York, at about 7:20 p.m. Wednesday when two cars separated from the engine, Amtrak spokesman Jason Abrams said in a statement. Of the 287 passengers and crew, he said, no one was injured. The passengers were transferred to a new train, Abrams said.CNN reached out to Amtrak for further details but has not heard back.Billy Osher-Dugan was traveling to spend Thanksgiving with his girlfriend when he saw the cars separate."It was packed," he said. "There were hardly any seats available."He heard a noise and turned around to see cars behind him rip apart from the train, he said. That's when one passenger pulled the emergency brake to stop the train and others -- upon smelling smoke -- grabbed the fire extinguisher.Luckily, he said, there was no fire and everyone was OK.Helen Mary Crane was with her son on the way to spend the holiday with her daughter. Crane said two cars were added to the train when she boarded in Rensselaer, New York, and that she and her son were told to sit in the first of the additions.Crane's car was one of the two to break off."As far as being with my son," she said. "I was terrified when I saw the sparks and smelled burning and then realized our car was no longer attached. I thought we would derail or be hit by the other train."She said she credits the man who pulled the emergency brake on the runaway cars for the safety of everyone. She identified him as Reuben Clarke, a student at Rensselaer Polytechnic Institute."He saved our lives tonight," Crane said. "Our car broke off from the rest of the train and was picking up speed. There was no Amtrak personnel in our car. Reuben calmly went into action and pulled the emergency brake at the front of the car. Thankful he was on the train with my son and I."The National Transportation Safety Board will not investigate since there were no injuries or a derailment, board spokesman Nicholas Worrell said.New York State Police are investigating the incident. 2147

I thought it was going to be a wonderful day. My high school, Marjory Stoneman Douglas, was full of cheerful students -- many of whom were celebrating Valentine's Day with one another. Even those who didn't have a Valentine seemed like they could find reasons to smile.  283
