The US Air Force ordered immediate inspections of its entire fleet of B-1 bombers Thursday over safety concerns related to its "drogue chute system" which is used to right the aircraft's ejection seat prior to the seat's main parachute deploying.While none of the planes are being allowed to fly, the order is technically not an official grounding of the fleet, as each individual aircraft will be allowed to immediately return to flying operations upon inspection."The safety stand-down will afford maintenance and Aircrew Flight Equipment technicians the necessary time to thoroughly inspect each aircraft," the Air Force's Global Strike Command said in a statement."As these inspections are completed and any issues are resolved, aircraft will return to flight," the statement added.Global Strike Command would not estimate how long the inspections would take.Air Force officials say the drogue chute problem is unrelated to a previous issue with the aircraft's ejection seat which had led to a similar safety stand-down last year.All of the Air Force's 61 B-1 bombers are currently stationed in the US so the order will not impact operations.The B-1 is a conventional bomber and was used to conduct airstrikes against Syrian military targets in 2018 following the regime's use of chemical weapons. 1313

The porch piracy problems were not all what they seemed.The idea was glorious: To get revenge on thieves swiping packages off doorsteps, ex-NASA engineer Mark Rober built parcels with a pound of glitter and fart spray that burst out when the lid was lifted. He also put phones in the package to record thieves' reactions and to capture their location.The video Rober released of five "glitter bombs" in action was the perfect antidote for anyone who'd ever arrived home to find only a doormat where a delivery should have been. They showed giant glitter messes and complaints about the stench (one thief even said he was worried about how his girlfriend would react to his smelly, sparkling car).But now, Rober is apologizing for footage of two of the glitter attacks, which he admits is "misleading."Rober explained that he'd asked his friends -- and friends of friends -- to try out his invention, even offering to pay those who could recover their packages.What Rober didn't know, he said, is that some people called on their own buddies to pretend to be robbers, then sent the sham reaction videos to Rober, who passed them off on social media -- unwittingly -- as authentic.Rober took to Twitter on Thursday to let his audience know about the mishap."From the footage I received from the phones which intentionally only record at specific times, this wasn't obvious to me," 1392

Thick, black graffiti sprayed onto a Russian polar bear's coat poses an extra threat to an animal already in danger, experts say.Video shared on social media shows a lumbering polar bear whose back had been branded with "T-34," the name of an old Soviet Union tank.The video was posted to Facebook on December 1 by Sergey Kavry, a World Wildlife Fund employee who lives in the remote Russian region.In the comments, Kavry said he obtained the video via WhatsApp from indigenous minorities in Chukotka, in Russia's far east, though it is not clear from the video where it was filmed.Polar bears are having to 620
