'It's getting dicey': The final fatal seconds of a military aviation disaster
Your web browser is no longer supported. To improve your experience update it here A last second evasive manoeuvre by an Army pilot saved the lives of four other airmen, according to military air safety investigators. The Defence Flight Safety Bureau found that Captain Danniel Lyon, who died along with three others in a July 2023 Taipan helicopter crash off Hamilton Island, managed to avoid a mid-air collision despite knowing his own aircraft was "unrecoverable". The DFSB has blamed spatial disorientation for the fatal Army helicopter crash, with Defence investigators also concluding it was "unlikely" a hi-tech helmet used by the pilots for night-time flights contributed to the disaster despite the equipment's clear "hazard". "It's getting dicey," Captain Lyon is recorded telling co-pilot Lieutenant Max Nugent in the cockpit voice recorder, five seconds into a left-hand turn in staggered formation with three other Taipan MHR-90 helicopters. Their chopper, codenamed Bushman 83, had just flown into rain showers and Lyon had taken the controls from Nugent in response to the poor conditions at 10:33pm and 34 seconds. "I'll just get around the corner for you mate… while we're dealing with the rain shower," he tells Nugent. Corporal Alex Naggs, Captain Danniel Lyon, Lieutenant Max Nugent and Warrant Officer Phil Laycock (L-R) died in the crash. (60 Minutes) At 10:36:04, two and a half minutes after Lyon took the controls of Bushman 83, it started to climb, from 224ft to a maximum of 362ft, 14 seconds later. Nine seconds into the climb, with the Taipan at 320ft, Lyons says to Nugent: "Have you still got em?" referring to Bushman 82, the aircraft flying ahead of them in the formation, to the right. Nugent replies calmly: "Yeah, still get em mate." DFSB investigators believe it was at this point that Lyon lost sight of Bushman 82. He quickly rolled the aircraft 31 degrees right before quickly rolling back left 8 degrees to establish a visual of the other aircraft.

At 10:36:19, Bushman 83 reached the top of its climb, now much higher than the three other helicopters in the formation. It is six seconds from disaster. Unaware that the pitch attitude had shifted from nose up to nose down, Lyon used the controls to pitch down, exacerbating the so-called "pushover". The aircraft went into a quickening descent, hitting the water at 10:36:25 – 21 seconds after it began to climb. When it hit to water it was travelling at 259kmh. Lyon, Nugent and aircrew Warrant Officer Phil Laycock and Corporal Alex Naggs were killed instantly. The DFSB report found that in the split seconds before the crash, when the aircraft was in its fatal plunge, Lyon realised Bushman 83 was at risk of crashing into Bushman 82 and took immediate diversionary steps, rolling the aircraft to the right. The wreckage the Taipan is removed from waters in the Whitsundays after the crash last year. (9News) "During the two and a half seconds after the pushover, (flight data recorder) analysis indicates that the relative distance between the two aircraft decreased from approximately 100 metres to 50 metres," the DFSB report says. "In response to this increasing closure, it is likely (Lyon) acted to avoid a potential mid-air collision with BSMN 82 by executing an avoidance turn to the right." Lyon's actions in these last seconds, when his own aircraft was "not recoverable", likely saved the lives of the four airmen in Bushman 82. Since the July 2023 crash there has been much focus on the hi-tech TopOwl helmets used by the pilots that night. The latest software upgrade for the TopOwl, HMSD v5.10, was found to carry significant risks, according to an experienced test pilot with the Army Aviation Test and Evaluation Section (AATES). The test pilots found that the helmet was a "substantial risk of multiple deaths" and an "unacceptable risk to flight safety" because when pilots looks to the left or the right, the pitch and roll displays inverted. Despite this stark warning, TopOwl 5.0 was put into service when Army Aviation conducted its own tests in benign conditions, finding it safe to deploy. DFSB confirmed that TopOwl had its problems but said it was likely not responsible for Lyon becoming spatially disoriented. "While both AATES and Standards Section test and evaluation reports agreed that there were deficiencies relating to attitude presentation, the two agencies disagreed on the severity of the hazard," DFSB said. "Regardless, the investigation determined that it was very unlikely the known hazards relating to the HMSD v5.10 contributed to the loss of Spatial Orientation. This conclusion was based on the Line of Sight of the BSMN 83 pilots, which was slightly offset from the aircraft's longitudinal axis, and that the pilots were likely looking 'through' the HMSD symbology to maintain attentional focus on BSMN 82."

Millions march in anti-Trump 'No-Kings' protests
Masses of demonstrators packed into streets, parks and plazas across the US to condemn President Donald Trump as authoritarian and dictator-like. Organisers of the "No Kings" demonstrations said millions had marched in hundreds of events. Governors across the US had urged calm and vowed no tolerance for violence, while some mobilised the National Guard ahead of marchers gathering. Confrontations were isolated. But police in Los Angeles, where protests over federal immigration enforcement raids erupted a week earlier and sparked demonstrations across the country, used tear gas and crowd-control munitions to clear out protesters after the formal event ended. In Salt Lake City, Utah, police said they are investigating a shooting "possibly associated" with a march through downtown that left a person with life-threatening injuries. A person of interest was in custody, police said. The march of several thousand people has just passed the downtown federal building before people started running, and responding officers told people to immediately take shelter, KSTU reported. Huge, boisterous crowds marched, danced, drummed, and chanted shoulder-to-shoulder in New York, Denver, Chicago, Austin and Los Angeles. Atlanta's 5,000-capacity event quickly reached its limit, with thousands more gathered outside barriers to hear speakers in front of the state Capitol. Trump was in Washington for a military parade marking the Army's 250th anniversary that coincides with the president's birthday. About 200 protesters assembled in northwest Washington's Logan Circle and chanted "Trump must go now" before erupting in cheers. In Culpepper, Virginia, police said one person was struck by an SUV when a 21-year-old driver intentionally accelerated his SUV into the crowd as protesters were leaving a rally. The driver was charged with reckless driving. "Today, across red states and blue, rural towns and major cities, Americans stood in peaceful unity and made it clear: we don't do kings," the No Kings Coalition said in a statement Saturday afternoon after many events had ended. In Los Angeles, as protesters passed National Guard troops or US Marines stationed at various buildings, most interactions were friendly, with demonstrators giving fist bumps or posing for selfies. But others chanted "shame" or "go home" at the troops. A few blocks from City Hall, protesters gathered in front of the downtown federal detention centre being guarded by a line of Marines and other law enforcement. It was the first time that the Marines, in combat gear and holding rifles, have appeared at a demonstration since they were deployed to city on Friday with the stated mission of defending federal property. The demonstration turned confrontational as police on horseback moved into the crowd and struck some people with wood rods and batons as they cleared the street in front of the federal building. Minnesota Governor Tim Walz and law enforcement encouraged people not to attend rallies "out of an abundance of caution" following the shootings of two Democratic state lawmakers. Tens of thousands still turned out for demonstrations in Duluth, Rochester and St. Paul, which included a march to the state Capitol. Walz cancelled his scheduled appearance at the St. Paul event. Authorities said the suspect in the Minneapolis shootings had "No Kings" flyers in his car and writings mentioning the names of the victims as well as other lawmakers and officials, though they could not say if he had any other specific targets. A rally at the Texas Capitol in Austin went off as planned despite state police briefly shutting down the building and the surrounding grounds after authorities said they received a "credible threat" to Democratic state lawmakers who were to attend. Dozens of state troopers swarmed through the grounds about four hours before the event, but the area was later opened and the rally started on time. The building remained closed. The Department of Public Safety later said one person was taken into custody "after a traffic stop in La Grange, Texas, about 105 kilometres east of Austin.

US father Travis Decker wanted on suspicion of murdering his three young daughters
A US man is wanted on suspicion of murder after his three young daughters were reported missing and then found dead. Travis Decker, 32, is wanted for three counts of murder and kidnapping, according to police in Wenatchee — a city in central Washington state, about 100 miles or two and a half hours east of Seattle. Police said it was unknown whether Decker, a former Army soldier with 'extensive training', was armed. Paityn, 9, Evelyn, 8, and Olivia, 5, were not returned home to their mother by Decker on Friday following a planned visit. She then reported them missing. Over the weekend, authorities looked for the children and for Decker, who was believed to be living out of a white 2017 GMC Sierra pickup with Washington plates. Decker's unoccupied truck was found on Monday near a campground west of the city of Leavenworth, which is about a half hour northwest of Wenatchee. Chelan County Sheriff's Office deputies found the girls' bodies about 75 to 100 yards away from the truck, The Seattle Times reported. Police believe the girls died from asphyxiation and reported that their wrists were zip-tied, court documents said. Anyone who may have seen Decker since Friday or knows his current location was asked to call 911. 'Due to safety concerns do not attempt to contact or approach Decker,' police said. The Wenatchee School District said the girls were students of Lincoln Elementary and that counselling services were available. The mother told police that Decker picked the girls up around 5pm but had not returned them by 8pm, and his phone went straight to voicemail, court documents said. The detective said she 'expressed concern because Decker reportedly has never done this before and … is currently experiencing some mental health issues'. 'What prompted her to call us was that … he was late returning the girls and had not communicated to her that he was going to be late, which was his typical fashion and so this was out of the ordinary,' Captain Brian Chance said. Washington State Patrol was contacted Friday night to request an Amber Alert, but it did not meet the required criteria, Wenatchee police said. The following day, Wenatchee detectives contacted the patrol with additional information that led to an Endangered Missing Person Alert being issued. The lacking criteria was suspected abduction and imminent peril of death or serious injury, director of public affairs for the state patrol Chris Loftis said. 'In this case, it was a parent with custodial privileges, and the children had not been returned home on time,' he said. 'But that's a rather common occurrence and not something where you just automatically assume abduction.' There was no indication Decker, a custodial parent who had the children for a visit, would harm them, Loftis said. 'We're people too, you know, so the loss of a child, the loss of two children, the loss of three children is … devastating,' he said. 'Everybody always looks to how we can improve.' The alert systems are constantly evolving and this could prompt further change, Loftis said: 'Obviously it didn't work this time. Obviously, we have three children that are dead.' Decker joined the Army in 2013 and transferred to the Washington National Guard in 2021, Washington Military Department spokesperson Karina Shagren said. He was a full-time member of the Guard until 2023 or 2024, when he switched to part-time. Decker stopped attending mandatory monthly drills a little over a year ago, and the Guard was in the process of a disciplinary discharge for him, Shagren said. 'This is an absolute tragedy,' Shagren said. 'We are mourning along with the community.' The Chelan County Sheriff's Office, which found the truck, was leading the search in the Okanogan Wenatchee National Forest area while other teams followed up on 'potential credible information and tips' regarding Decker's location, the agency said in a statement. The agency was working with US Marshals to locate and apprehend Decker and the search continued Tuesday evening. A reward of up to $US20,000 ($A30,700) was available for information leading directly to his arrest.
